75-641: Ariane 5 is a retired European heavy-lift space launch vehicle operated by Arianespace for the European Space Agency (ESA). It was launched from the Guiana Space Centre (CSG) in French Guiana . It was used to deliver payloads into geostationary transfer orbit (GTO), low Earth orbit (LEO) or further into space. The launch vehicle had a streak of 82 consecutive successful launches between 9 April 2003 and 12 December 2017. Since 2014, Ariane 6 ,
150-509: A SYLDA ( Système de Lancement Double Ariane , meaning "Ariane Double-Launch System") carrier system. Up to three, somewhat smaller, main satellites are possible depending on size using a SPELTRA ( Structure Porteuse Externe Lancement Triple Ariane , which translates to "Ariane Triple-Launch External Carrier Structure"). Up to eight secondary payloads, usually small experiment packages or minisatellites , could be carried with an ASAP (Ariane Structure for Auxiliary Payloads) platform. Following
225-424: A 5.4 m (18 ft) diameter by 30.5 m (100 ft) high tank with two compartments, one for liquid oxygen and one for liquid hydrogen , and a Vulcain 2 engine at the base with a vacuum thrust of 1,390 kN (310,000 lb f ). The H173 EPC weighed about 189 t (417,000 lb), including 175 t (386,000 lb) of propellant. After the main cryogenic stage runs out of fuel, it re-entered
300-716: A Polaris A-1 on 20 July 1960. Fifty-two days later, the Soviet Union made its first successful underwater launch of a submarine ballistic missile in the White Sea, on 10 September 1960 from the same converted Project 611 ( NATO reporting name Zulu-IV class) submarine that first launched the R-11FM. The Soviets were only a year behind the US with their first SSBN, the ill-fated K-19 of Project 658 (Hotel class), commissioned in November 1960. However,
375-402: A design might not have been possible if the higher Max-Q for the launch of this launch vehicle would have posed a constraint on the mass delivered to orbit. The design brief of the next generation launch vehicle Ariane 6 called for a lower-cost and smaller launch vehicle capable of launching a single satellite of up to 6,500 kg (14,300 lb) to GTO. However, after several permutations
450-484: A different target. Although the US did not commission any new SSBNs from 1967 through 1981, it did introduce two new SLBMs. Thirty-one of the 41 original US SSBNs were built with larger diameter launch tubes with future missiles in mind. In the early 1970s the Poseidon (C-3) missile entered service, and those 31 SSBNs were backfitted with it. Poseidon offered a massive MIRV capability of up to 14 warheads per missile. Like
525-571: A direct successor system, first launched in 2024. The system was designed as an expendable launch vehicle by the Centre national d'études spatiales (CNES), the French government's space agency, in cooperation with various European partners. Despite not being a direct derivative of its predecessor launch vehicle program, it was classified as part of the Ariane rocket family . Aérospatiale , and later ArianeGroup ,
600-721: A lone Typhoon used as a testbed for new missiles (the R-39s unique to the Typhoons were reportedly scrapped in 2012). Upgraded missiles such as the R-29RMU Sineva (SS-N-23 Sineva) were developed for the Deltas. In 2013 the Russians commissioned the first Borei-class submarine , also called the Dolgorukiy class after the lead vessel. By 2015 two others had entered service. This class is intended to replace
675-576: A new commercial payload lifting record of 8,200 kg (18,100 lb). The dual-payload consisted of the Thaicom 5 and Satmex 6 satellites. On 4 May 2007, the Ariane 5ECA set another new commercial record, lifting into transfer orbit the Astra 1L and Galaxy 17 communication satellites with a combined weight of 8,600 kg (19,000 lb), and a total payload weight of 9,400 kg (20,700 lb). This record
750-717: A range of 7,700 kilometres (4,200 nmi), entered service on the first Delta-I boat in 1972, before the Yankee class was even completed. A total of 43 Delta-class boats of all types entered service 1972–90, with the SS-N-18 on the Delta III class and the R-29RM Shtil (SS-N-23) on the Delta IV class. The new missiles had increased range and eventually multiple independently targetable reentry vehicles ( MIRV ), multiple warheads that could each hit
825-569: A telemetry loss occurred between the launch vehicle and the ground controllers. It was later confirmed, about 1 hour and 20 minutes after launch, that both satellites were successfully separated from the upper stage and were in contact with their respective ground controllers, but that their orbital inclinations were incorrect as the guidance systems might have been compromised. Therefore, both satellites conducted orbital procedures, extending commissioning time. SES-14 needed about 8 weeks longer than planned commissioning time, meaning that entry into service

#1732870129506900-778: A third burn after ATV deployment to de-orbit the stage. This procedure was repeated for all subsequent ATV flights. Ariane 5ECA used the ESC ( Étage Supérieur Cryotechnique — Cryogenic Upper Stage), which was fueled by liquid hydrogen and liquid oxygen. The ESC used the HM7B engine previously used in the Ariane 4 third stage. The propellent load of 14.7 tonne allowed the engine to burn for 945 seconds while providing 6.5 tonne of thrust. The ESC provided roll control during powered flight and full attitude control during payload separation using hydrogen gas thrusters. Oxygen gas thrusters allowed longitudinal acceleration after engine cutoff. The flight assembly included
975-600: Is a ballistic missile capable of being launched from submarines . Modern variants usually deliver multiple independently targetable reentry vehicles (MIRVs), each of which carries a nuclear warhead and allows a single launched missile to strike several targets. Submarine-launched ballistic missiles operate in a different way from submarine-launched cruise missiles . Modern submarine-launched ballistic missiles are closely related to intercontinental ballistic missiles (ICBMs), with ranges of over 5,500 kilometres (3,000 nmi), and in many cases SLBMs and ICBMs may be part of
1050-455: The Ariane 4 where efficiency considerations (the computer running the software had an 80% maximum workload requirement) led to four variables being protected with a handler while three others, including the horizontal bias variable, were left unprotected because it was thought that they were "physically limited or that there was a large margin of safety". The software, written in Ada , was included in
1125-536: The Cold War , as they can hide from reconnaissance satellites and fire their nuclear weapons with virtual impunity. This makes them immune to a first strike directed against nuclear forces, allowing each side to maintain the capability to launch a devastating retaliatory strike , even if all land-based missiles have been destroyed. This relieves each side of the necessity to adopt a launch on warning posture, with its attendant risk of accidental nuclear war. Additionally,
1200-863: The Long March 5 and the Proton-M . In addition, the Angara A5 , the Falcon 9 Block 5 , the Falcon Heavy , the Vulcan Centaur , Ariane 6 , and New Glenn are designed to provide heavy-lift capabilities in at least some configurations but have not yet been proven to carry a 20-tonne payload into LEO. Several other heavy-lift rockets are in development. An HLV is between medium-lift launch vehicles and super heavy-lift launch vehicles . Submarine-launched ballistic missile A submarine-launched ballistic missile ( SLBM )
1275-808: The Naval Submarine Base King's Bay in Georgia was built for the Trident I-equipped force. Both the United States and the Soviet Union commissioned larger SSBNs designed for new missiles in 1981. The American large SSBN was the Ohio class , also called the "Trident submarine", with the largest SSBN armament ever of 24 missiles, initially Trident I but built with much larger tubes for the Trident II (D-5) missile , which entered service in 1990. The entire class
1350-450: The nuclear test series Operation Dominic . The first Soviet SSBN with 16 missiles was the Project 667A (Yankee class), which first entered service in 1967 with 32 boats completed by 1974. By the time the first Yankee was commissioned the US had built 41 SSBNs, nicknamed the " 41 for Freedom ". The short range of the early SLBMs dictated basing and deployment locations. By the late 1960s
1425-418: The Ariane 5 through the reuse of an entire Ariane 4 subsystem despite the fact that the particular software containing the bug, which was just a part of the subsystem, was not required by the Ariane 5 because it has a different preparation sequence than the Ariane 4. The second test flight (L502, on 30 October 1997) was a partial failure. The Vulcain nozzle caused a roll problem, leading to premature shutdown of
1500-455: The Ariane 5ECA took place on 12 February 2005. The payload consisted of the XTAR-EUR military communications satellite, a 'SLOSHSAT' small scientific satellite and a MaqSat B2 payload simulator. The launch had been scheduled for October 2004, but additional testing and a military launch (of a Helios 2A observation satellite) delayed the attempt. On 11 August 2005, the first Ariane 5GS (featuring
1575-538: The Ariane 5ECA's improved solid motors) boosted Thaicom 4 , the heaviest telecommunications satellite to date at 6,505 kg (14,341 lb), into orbit. On 16 November 2005, the third Ariane 5ECA launch (the second successful ECA launch) took place. It carried a dual payload consisting of Spaceway F2 for DirecTV and Telkom-2 for PT Telekomunikasi of Indonesia . This was the launch vehicle's heaviest dual payload to date, at more than 8,000 kg (18,000 lb). On 27 May 2006, an Ariane 5ECA launch vehicle set
SECTION 20
#17328701295061650-531: The Ariane 5ME with total development effort expected to cost €1 billion. On 21 November 2012, ESA agreed to continue with the Ariane 5ME to meet the challenge of lower priced competitors. It was agreed the Vinci upper stage would also be used as the second stage of a new Ariane 6, and further commonality would be sought. Ariane 5ME qualification flight was scheduled for mid-2018, followed by gradual introduction into service. On 2 December 2014, ESA decided to stop funding
1725-459: The Ariane programme, but this was most likely an inference based on early blueprints of the Ariane 6 having a central P80 booster and 2-4 around the main one. The incorporation of the ESC-B with the improvements to the solid motor casing and an uprated Vulcain engine would have delivered 27,000 kg (60,000 lb) to LEO. This would have been developed for any lunar missions but the performance of such
1800-561: The Guiana Space Center for analysis. Prior to that mission, the last such recovery and testing was done in 2003. The French M51 submarine-launched ballistic missile (SLBM) shared a substantial amount of technology with these boosters. In February 2000, the suspected nose cone of an Ariane 5 booster washed ashore on the South Texas coast, and was recovered by beachcombers before the government could get to it. The second stage
1875-555: The Hotel class carried only three R-13 missiles (NATO reporting name SS-N-4) each and had to surface and raise the missile to launch. Submerged launch was not an operational capability for the Soviets until 1963, when the R-21 missile (SS-N-5) was first backfitted to Project 658 (Hotel class) and Project 629 (Golf class) submarines. The Soviet Union was able to beat the U.S. in launching and testing
1950-822: The Navy, beginning in late 1955. However, at the Project Nobska submarine warfare conference in 1956, physicist Edward Teller stated that a physically small one-megaton warhead could be produced for the relatively small, solid-fueled Polaris missile , and this prompted the Navy to leave the Jupiter program in December of that year. Soon Chief of Naval Operations Admiral Arleigh Burke concentrated all Navy strategic research on Polaris , still under Admiral Raborn's Special Project Office. All US SLBMs have been solid-fueled while all Soviet and Russian SLBMs have been liquid-fueled except for
2025-557: The Polaris A-3 was deployed on all US SSBNs with a range of 4,600 kilometres (2,500 nmi), a great improvement on the 1,900 kilometres (1,000 nmi) range of Polaris A-1. The A-3 also had three warheads that landed in a pattern around a single target. The Yankee class was initially equipped with the R-27 Zyb missile (SS-N-6) with a range of 2,400 kilometres (1,300 nmi). The US was much more fortunate in its basing arrangements than
2100-490: The Russian RSM-56 Bulava , which entered service in 2014. The world's first operational nuclear-powered ballistic missile submarine (SSBN) was USS George Washington (SSBN-598) with 16 Polaris A-1 missiles, which entered service in December 1959 and conducted the first SSBN deterrent patrol November 1960 – January 1961. George Washington also conducted the first successful submerged SLBM launch with
2175-568: The Soviets, the US also desired a longer-range missile that would allow SSBNs to be based in CONUS. In the late 1970s the Trident I (C-4) missile with a range of 7,400 kilometres (4,000 nmi) and eight MIRV warheads was backfitted to 12 of the Poseidon-equipped submarines. The SSBN facilities (primarily a submarine tender and floating dry dock ) of the base at Rota, Spain were disestablished and
2250-637: The Soviets. Thanks to NATO and the US possession of Guam , US SSBNs were permanently forward deployed at Advanced Refit Sites in Holy Loch , Scotland, Rota, Spain , and Guam by the middle 1960s, resulting in short transit times to patrol areas near the Soviet Union. The SSBN facilities at the Advanced Refit Sites were austere, with only a submarine tender and floating dry dock . Converted merchant ships designated T-AKs ( Military Sealift Command cargo ships) were provided to ferry missiles and supplies to
2325-601: The US with the collapse of the Soviet Union and the end of the Cold War in 1991. The US rapidly decommissioned its remaining 31 older SSBNs, with a few converted to other roles, and the base at Holy Loch was disestablished. Most of the former Soviet SSBN force was gradually scrapped under the provisions of the Nunn–Lugar Cooperative Threat Reduction agreement through 2012. By that time the Russian SSBN force stood at six Delta-IVs, three Delta-IIIs, and

2400-560: The United States ( Operation Paperclip ) and for the Soviet Union on their SLBM programs. These and other early SLBM systems required vessels to be surfaced when they fired missiles, but launch systems were adapted to allow underwater launching in the 1950-1960s. A converted Project 611 (Zulu-IV class) submarine launched the world's first SLBM, an R-11FM (SS-N-1 Scud-A, naval variant of the SS-1 Scud ) on 16 September 1955. Five additional Project V611 and AV611 (Zulu-V class) submarines became
2475-463: The Vehicle Equipment Bay, with flight electronics for the entire rocket, and the payload interface and structural support. The payload and all upper stages were covered at launch by a fairing for aerodynamic stability and protection from heating during supersonic flight and acoustic loads. It was jettisoned once sufficient altitude has been reached, typically above 100 km (62 mi). It

The US is building a replacement for the Ohio class ; however, the first of the class wasn't laid down until October 2020. Ballistic missile submarines have been of great strategic importance for the United States, Russia, and other nuclear powers since they entered service in
2625-530: The atmosphere for an ocean splashdown. Attached to the sides were two P241 (P238 for Ariane 5G and G+) solid rocket boosters (SRBs or EAPs from the French Étages d'Accélération à Poudre ), each weighing about 277 t (611,000 lb) full and delivering a thrust of about 7,080 kN (1,590,000 lb f ). They were fueled by a mix of ammonium perchlorate (68%) and aluminium fuel (18%) and HTPB (14%). They each burned for 130 seconds before being dropped into
2700-594: The continental United States ( CONUS ) at risk. This resulted in only a small percentage of the Soviet force occupying patrol areas at any time, and was a great motivation for longer-range Soviet SLBMs, which would allow them to patrol close to their bases, in areas sometimes referred to as "deep bastions". These missiles were the R-29 Vysota series (SS-N-8, SS-N-18, SS-N-23), equipped on Projects 667B, 667BD, 667BDR, and 667BDRM (Delta-I through Delta-IV classes). The SS-N-8, with
2775-484: The core stage. The upper stage operated successfully, but it could not reach the intended orbit. A subsequent test flight (L503, on 21 October 1998) proved successful and the first commercial launch (L504) occurred on 10 December 1999 with the launch of the XMM-Newton X-ray observatory satellite. Another partial failure occurred on 12 July 2001, with the delivery of two satellites into an incorrect orbit, at only half
2850-596: The deployment of highly accurate missiles on ultra-quiet submarines allows an attacker to sneak up close to the enemy coast and launch a missile on a depressed trajectory (a non-optimal ballistic trajectory which trades off reduced throw-weight for a faster and lower path, effectively reducing the time between launch and impact), thus opening the possibility of a decapitation strike . Specific types of SLBMs (current, past and under development) include: Some former Russian SLBMs have been converted into Volna and Shtil' launch vehicles to launch satellites – either from

These were all in the Pacific, and the Guam SSBN base was disestablished; the first several Ohio -class boats used new Trident facilities at Naval Submarine Base Bangor , Washington . Eighteen Ohio -class boats were commissioned by 1997, four of which were converted as cruise missile submarines (SSGN) in the 2000s to comply with START I treaty requirements. The Soviet large SSBN
3075-450: The failure of the first ECA flight in 2002, combined with a deteriorating satellite industry, caused ESA to cancel development in 2003. Development of the Vinci engine continued, though at a lower pace. The ESA Council of Ministers agreed to fund development of the new upper stage in November 2008. In 2009, EADS Astrium was awarded a €200 million contract, and on 10 April 2012 received another €112 million contract to continue development of

3150-611: The finalized design was nearly identical in performance to the Ariane 5, focusing instead on lowering fabrication costs and launch prices. As of March 2014, Ariane 6 was projected to be launched for about €70 million per flight, about half of the Ariane 5 price. Initially development of Ariane 6 was projected to cost €3.6 billion. In 2017, the ESA set 16 July 2020 as the deadline for the first flight. The Ariane 6 successfully completed its maiden flight on 9 July 2024. Ariane 5's first test flight ( Ariane 5 Flight 501 ) on 4 June 1996 failed, with

On 27 September 2003, the last Ariane 5G boosted three satellites (including the first European lunar probe, SMART-1 ), in Flight 162. On 18 July 2004, an Ariane 5G+ boosted what was at the time the heaviest telecommunication satellite ever, Anik F2 , weighing almost 6,000 kg (13,000 lb). The first successful launch of

The payload record was pushed a further 5 kg (11 lb), up to 10,735 kg (23,667 lb) on 24 August 2016 with the launch of Intelsat 33e and Intelsat 36 . On 1 June 2017, the payload record was broken again to 10,865 kg (23,953 lb) carrying ViaSat-2 and Eutelsat-172B . In 2021 VA-255 put 11,210 kg into GTO. On 25 January 2018, an Ariane 5ECA launched SES-14 and Al Yah 3 satellites. About 9 minutes and 28 seconds after launch,

The ESA Artemis telecommunications satellite was able to reach its intended orbit on 31 January 2003, through the use of its experimental ion propulsion system. The next launch did not occur until 1 March 2002, when the Envisat environmental satellite successfully reached an orbit of 800 km (500 mi) above the Earth in the 11th launch. At 8,111 kg (17,882 lb), it

This mission anomaly marked the end of 82nd consecutive success streak since 2003. Ariane 5 launch vehicles had accumulated 117 launches, 112 of which were successful, yielding a 95.7% success rate. Between April 2003 and December 2017, Ariane 5 flew 83 consecutive missions without failure, but

Ariane 5 flew its final mission on 5 July 2023. Ariane 5's cryogenic H173 main stage (H158 for Ariane 5G, G+, and GS) was called the EPC ( Étage Principal Cryotechnique — Cryotechnic Main Stage). It consisted of
3675-646: The launch vehicle suffered a partial failure in January 2018. All launches are from Guiana Space Centre , ELA-3 . Heavy-lift launch vehicle A heavy-lift launch vehicle (HLV) is an orbital launch vehicle capable of generating a large amount of lift to reach its intended orbit. Heavy-lift launch vehicles generally are capable of lifting payloads between 20,000 to 50,000 kg (44,000 to 110,000 lb) (by NASA classification) or between 20,000 to 100,000 kilograms (44,000 to 220,000 lb) (by Russian classification) into low Earth orbit (LEO). As of 2024 , operational heavy-lift launch vehicles include
3750-748: The new Ariane 6 . With first flight planned for 2018, it would have become ESA's principal launcher until the arrival of the new Ariane 6 version. ESA halted funding for the development of Ariane 5ME in late 2014 to prioritize development of Ariane 6. The Ariane 5ME was to use a new upper stage, with increased propellant volume, powered by the new Vinci engine . Unlike the HM-7B engine, it was to be able to restart several times, allowing for complex orbital maneuvers such as insertion of two satellites into different orbits, direct insertion into geosynchronous orbit, planetary exploration missions, and guaranteed upper stage deorbiting or insertion into graveyard orbit . The launcher

The SRBs were usually allowed to sink to the bottom of the ocean, but, like the Space Shuttle Solid Rocket Boosters , they could be recovered with parachutes, and this was occasionally done for post-flight analysis. Unlike Space Shuttle SRBs, Ariane 5 boosters were not reused. The most recent attempt was for the first Ariane 5 ECA mission in 2009. One of the two boosters was successfully recovered and returned to

According to Rudiger Albat, the program manager for Ariane 5, efforts had been made to select components for this flight that had performed especially well during pre-flight testing, including "one of the best Vulcain engines that we've ever built." On 22 April 2011, the Ariane 5ECA flight VA-201 broke a commercial record, lifting Yahsat 1A and Intelsat New Dawn with a total payload weight of 10,064 kg (22,187 lb) to transfer orbit. This record
4800-401: Was later broken again during the launch of Ariane 5ECA flight VA-208 on 2 August 2012, lifting a total of 10,182 kg (22,447 lb) into the planned geosynchronous transfer orbit, which was broken again 6 months later on flight VA-212 with 10,317 kg (22,745 lb) sent towards geosynchronous transfer orbit. In June 2016, the GTO record was raised to 10,730 kg (23,660 lb), on
4875-399: Was launched into a lower-energy orbit than a usual GTO, with its initial apogee at roughly 17,900 km (11,100 mi). On 28 October 2010, an Ariane 5ECA launched Eutelsat 's W3B (part of its W Series of satellites) and Broadcasting Satellite System Corporation (B-SAT)'s BSAT-3b satellites into orbit. But the W3B satellite failed to operate shortly after the successful launch and
4950-409: Was lost in the Atlantic Ocean . The fault was determined to have been caused by a leak in coolant pipes allowing the nozzle to overheat. After this failure, Arianespace SA delayed the expected January 2003 launch for the Rosetta mission to 26 February 2004, but this was again delayed to early March 2004 due to a minor fault in the foam that protects the cryogenic tanks on the Ariane 5. The failure of
5025-415: Was made by Ruag Space and since flight VA-238 it was composed of 4 panels. As of November 2014, the Ariane 5 commercial launch price for launching a "midsize satellite in the lower position" was approximately €50 million, competing for commercial launches in an increasingly competitive market . The heavier satellite was launched in the upper position on a typical dual-satellite Ariane 5 launch and
5100-468: Was made of filament wound graphite epoxy, much lighter than the current stainless steel casing. A new composite steerable nozzle was developed while new thermal insulation material and a narrower throat improved the expansion ratio and subsequently the overall performance. Additionally, the nozzle had electromechanical actuators which replaced the heavier hydraulic ones used for thrust vector control. These developments could maybe have made their way back into
5175-399: Was on top of the main stage and below the payload. The original Ariane — Ariane 5G — used the EPS ( Étage à Propergols Stockables — Storable Propellant Stage), which was fueled by monomethylhydrazine (MMH) and nitrogen tetroxide , containing 10,000 kg (22,000 lb) of storable propellant . The EPS was subsequently improved for use on the Ariane 5G+, GS, and ES. The EPS upper stage
5250-415: Was priced higher than the lower satellite, on the order of €90 million as of 2013. Total launch price of an Ariane 5 – which could transport up to two satellites to space, one in the "upper" and one in the "lower" positions – was around €150 million as of January 2015. The Ariane 5 ME (Mid-life Evolution) was in development into early 2015, and was seen as a stopgap between Ariane 5ECA/Ariane 5ES and
5325-443: Was reported early September instead of July. Nevertheless, SES-14 is still expected to be able to meet the designed lifetime. This satellite was originally to be launched with more propellant reserve on a Falcon 9 launch vehicle since the Falcon 9, in this specific case, was intended to deploy this satellite into a high inclination orbit that would require more work from the satellite to reach its final geostationary orbit. The Al Yah 3
5400-597: Was the Project 941 Akula , famous as the Typhoon-class (and not to be confused with the Project 971 Shchuka attack submarine , called "Akula" by NATO). The Typhoons were the largest submarines ever built at 48,000 tons submerged. They were armed with 20 of the new R-39 Rif (SS-N-20) missiles with a range of 8,300 kilometres (4,500 nmi) and 10 MIRV warheads. Six Typhoons were commissioned in 1981–89. New SSBN construction terminated for over 10 years in Russia and slowed in
5475-472: Was the heaviest single payload until the launch of the first ATV on 9 March 2008, at 19,360 kg (42,680 lb). The first launch of the ECA variant on 11 December 2002 ended in failure when a main booster problem caused the rocket to veer off-course, forcing its self-destruction three minutes into the flight. Its payload of two communications satellites ( STENTOR and Hot Bird 7 ), valued at about €630 million,
5550-553: Was the prime contractor for the manufacturing of the vehicles, leading a multi-country consortium of other European contractors. Ariane 5 was originally intended to launch the Hermes spacecraft, and thus it was rated for human space launches . Since its first launch, Ariane 5 was refined in successive versions: "G", "G+", "GS", "ECA", and finally, "ES". The system had a commonly used dual-launch capability, where up to two large geostationary belt communication satellites can be mounted using
5625-419: Was written off as a total loss due to an oxidizer leak in the satellite's main propulsion system. The BSAT-3b satellite, however, is operating normally. The VA253 launch on 15 August 2020 introduced two small changes that increased lift capacity by about 85 kg (187 lb); these were a lighter avionics and guidance-equipment bay, and modified pressure vents on the payload fairing, which were required for
