Mounted at the base of each pair of antennas are two high-power amplifiers associated with
1679-416: Is somewhat unusual in that it is a "detection-to-kill" system, meaning that a single unit performs all search, identification, track, and engagement functions. Most other SAM systems, by contrast, require several different radars to perform all functions necessary to detect and engage targets. The beam created by the Patriot's flat phased array radar is comparatively narrow and highly agile compared to that of
1752-421: Is trainable in azimuth and elevates to a fixed, elevated launch position. Precise aiming of the launcher before launch is not necessary; thus, no extra lags are introduced into system reaction time.

A fin servo system positions the fins. The fin servo system consists of hydraulic actuators and valves and an electrohydraulic power supply. The electrohydraulic power consists of a battery, motor pump, oil reservoir, gas pressure bottle, and accumulator. Patriot
3358-453: The antennas and the radios in the co-located shelter. It is through these antennas that the ECS and ICC send their respective UHF "shots" to create the PADIL network. The polarity of each shot can be changed by adjusting the "feedhorn" to a vertical or horizontal position. This enables a greater chance of communication shots reaching their intended target when terrain obstacles may otherwise obscure
3431-457: The antennas of the OE-349 Antenna Mast Group, which are used to create UHF "shots" between sister Patriot batteries and their associated ICC. This creates a secure, real-time data network (known as PADIL, Patriot Data Information Link) that allows the ICC to centralize control of its subordinate firing batteries. The RLRIU functions as the primary router for all data coming into the ECS. The RLRIU gives

The test was a success, with the interceptor destroying the Scud that flew a 300 km (190 mi) trajectory at an altitude of 40 km (25 mi), west of San Nicolas Island . This was the seventh test of the complete system, the first interception of
3577-508: The beam protocol while in "TBM search" was further modified. PAC-2 saw Patriot's first major missile upgrade, with the introduction of the MIM-104C, or PAC-2 missile. This missile was optimized for ballistic missile engagements. Major changes to the PAC-2 missile were the size of the projectiles in its blast-fragmentation warhead, changed from around 2 grams to around 45 grams, and the timing of

The PAC-2 missile is 5.8 metres (19 ft 0 in) long, weighs about 900 kilograms (2,000 lb), and is propelled by a solid-fueled rocket motor. The PAC-2 family of missiles all have a fairly standard design, the only differences between the variants being certain internal components. They consist of (from front to rear)
3723-476: The horizon. Because of this, it was necessary to retain the search functions for traditional atmospheric threats in a separate search program, which could be easily toggled by the operator based on the expected threat. The ballistic missile defense capability changed the way Patriot defended targets. Instead of being used as a system to defend a significant area against enemy air attack, it was now used to defend much smaller "point" targets, which needed to lie within

The LEM is used for the real-time implementation of launcher operations requested via data link from the ECS. The LMA physically erects and rotates the launcher's platform and its missiles. The LIG connects the missiles themselves to
3869-575: The launcher via the Launcher Missile Round Distributor (LMRD). The first fielded variant was the MIM-104A "Standard". It was optimized solely for engagements against aircraft and had very limited capability against ballistic missiles. It had a range of 70 km (43 mi), and a speed in excess of Mach 2. The MIM-104B "anti-standoff jammer" (ASOJ) is a missile designed to seek out and destroy ECM emitters. The MIM-104C PAC-2 missile

It was designed as a 24-bit parallel militarized computer with fixed- and floating-point capability, organized in a multiprocessor configuration that operates at a maximum clock rate of 6 MHz . Compared to modern personal computers, this represents very limited processing power, so the computer has been upgraded several times during Patriot's service life. The latest variant fielded in 2013 has performance improved by several orders of magnitude. The DLT connects
4088-494: The operator. During the late 1980s, tests began to indicate that, although Patriot was certainly capable of intercepting inbound ballistic missiles, it was questionable whether the MIM-104A/B missile was capable of destroying them reliably. This necessitated the introduction of the PAC-2 missile and system upgrade. For the system, the PAC-2 upgrade was similar to the PAC-1 upgrade. Radar search algorithms were further optimized, and
4161-429: The original GEM missile was a new, faster proximity fuzed warhead. Tests had indicated that the fuze on the original PAC-2 missiles were detonating their warheads too late when engaging ballistic missiles with an extremely steep ingress, and as such it was necessary to shorten this fuze delay. The GEM missile was given a new "low noise " seeker head designed to reduce interference in front of the missile's radar seeker, and

This variant is designed to help Patriot engage and destroy ECM aircraft at standoff ranges. It works similar to an anti-radiation missile in that it flies a highly lofted trajectory and then locates, homes in on , and destroys the most significant emitter in an area designated by
4672-641: The system's TBM "footprint". The footprint is the area on the ground that Patriot can defend against inbound ballistic missiles. During the 1980s, Patriot was upgraded in relatively minor ways, mostly via its software. The most significant of these was a special upgrade to discriminate and intercept artillery rockets in the vein of the multiple rocket launcher , which was seen as a significant threat from North Korea. This feature has not been used in combat and has since been deleted from U.S. Army Patriot systems, though it remains in South Korean systems. Another upgrade
