64-488: A compass , a marine chronometer , two-way radios , and radiotelephone , etc. A flying bridge, also known as "monkey island", is an open area on top of a surface ship that provides unobstructed views of the fore, aft, and the sides of a vessel. It serves as an operating station for the ship's officers, such as the captain or officer of the watch . Prior to World War II, virtually every sailing ship , steamship , monitor , paddle steamer , or large pleasure ship had

96-435: A compass platform . This was usually a tower, where a magnetic compass could be sited far away as possible from the ferrous interference of the hulk of the ship. Many ships still have a flying bridge , a platform atop the pilot house, open to weather, containing a binnacle and voice tubes to allow the conning officer to direct the ship from a higher position during fair weather conditions. Larger warships may have

128-420: A navigation bridge , which is used for the actual conning of the ship, and a separate admiral's bridge can be provided in flagships , where the admiral can exercise control over the squadron of ships without interfering with the captain's command of the vessel. In older warships, a heavily armored conning tower was often provided, where the vital command staff could be located under protection to ensure that

160-651: A town in Pennsylvania , was a single-turreted Canonicus -class monitor built for the Union Navy during the American Civil War . Completed after the end of the war, Ajax was laid up until 1871, although she received her new name in 1869. The ship was briefly activated in 1871, before a much longer commission began in 1874–1875. She was assigned to the North Atlantic Squadron during this time. Ajax

192-443: A flying bridge above the main bridge. Flying bridges were generally not enclosed at all (although sometimes they were partially enclosed), and often had little equipment—usually just a speaking tube or telephone to allow communication with the helmsman or wheelman on the main bridge. On military warships after 1914, the flying bridge was usually the station for the air defense officer and the gunnery officer. The amount of equipment on

224-454: A flying bridge varies widely with the need of the captain. During World War II, for example, American submarine chaser surface ships had a well-outfitted flying bridge which usually contained a pelorus , signal lamps, telescope , and voice tube to permit the captain to command the ship. U.S. Navy attack transport ships could be outfitted with either 20mm or 40mm automatic cannons on their flying bridges. Flying bridges were almost always

256-408: A high-ranking officer such as an admiral could conduct fleet operations, plan strategy, and conduct large battles. Some flying bridges have "bridge wings", open areas which thrust outward from the flying bridge over the sides of the vessel by approximately 10 to 15 feet (3.0 to 4.6 m) to allow an officer to see the side of their ship while docking or working with smaller vessels. A bridge wing

288-458: A maximum draft of 13 ft 6 in (4.11 m). Ajax had a tonnage of 1,034 tons burthen and displaced 2,100 long tons (2,100  t ). Her crew consisted of 100 officers and enlisted men. Ajax was powered by a two-cylinder horizontal Ericsson vibrating-lever steam engine that drove one propeller using steam generated by four Stimers horizontal fire-tube boilers . The 320- indicated-horsepower (240 kW) engine gave

320-459: A ship may be located on the bridge or in a separate chart room, nearby. It includes a table sized for nautical charts where calculations of course and location are made. The navigator plots the course to be followed by the ship on these charts. Besides the desk and the navigation charts, the area contains navigational instruments that may include electronic equipment for a Global Positioning System receiver and chart display, fathometer ,

352-419: A ship with functions similar to a bridge. Depending upon the design and layout of a ship, some of these terms may be interchangeable. Traditionally, sailing ships were commanded from the quarterdeck , aft of the mainmast , where the ship's wheel was located (as it was close to the rudder ). A wheelhouse was a small enclosure around the ship's wheel on the quarterdeck of sailing ships . On modern ships

384-433: A vessel on passage. Such equipment will vary with ship type, but generally includes a GPS navigation device , a Navtex receiver, an ECDIS or chart system, one or more radars , a communications system (including distress calling equipment), engine ( telegraph ) controls, a wheel/autopilot system, a magnetic compass (for redundancy and cross check capability) and light/sound signalling devices. The navigation station of

416-444: The engine officer in the engine room by an engine order telegraph that displayed the captain's orders on a dial. The engine officer would ensure that the correct combination of steam pressure and engine revolutions were applied. Weatherproof pilot houses supplanted open bridges so that the pilot , who was traditionally the ship's navigating officer, could issue commands from shelter. Iron , and later steel , ships also required

448-421: The wheelhouse or pilothouse refers to the bridge of smaller motor vessels, such as tugs . With the arrival of paddle steamers , engineers required a platform from which they could inspect the paddle wheels and where the captain 's view would not be obstructed by the paddle houses. A raised walkway, literally a bridge, connecting the paddle houses was therefore provided. When the screw propeller superseded

480-526: The North Atlantic Squadron and was based at Key West, until she was decommissioned again on 27 July 1875, and laid up at Port Royal , South Carolina. Recommissioned on 5 November 1875, the ship remained at Port Royal, until moved to the James River . She was moored at Brandon and at City Point , Virginia, before being placed in ordinary at Richmond , on 30 June 1891. On 26 September 1895, Ajax

512-472: The command of Lieutenant Commander Charles Love Franklin, and transferred to Key West , Florida, to participate with the North Atlantic Squadron on coast defense maneuvers. She was decommissioned on 1 July 1871, and laid up at the Philadelphia Navy Yard . After a thorough overhaul , Ajax was recommissioned on 13 January 1874, with Commander Joseph N. Miller in command. The ship was assigned to

544-412: The full range of controls of the pilot house. On larger small vessels, the flying bridge may actually be enclosed, in which case it is more properly called an "upper pilot house" or "upper bridge". Warships that were also flagships (had a flag officer onboard) sometimes contained a flag bridge . Also known as the "admiral's bridge", these were a bridge below the main bridge on a command warship where

576-413: The highest bridge on the ship. They were usually above the flag bridge. Since the 1980s, large pleasure craft may have a flying bridge toward the stern that is used as additional outdoor seating space and a place to store a tender . On the smallest surface vessels, such as a sport fishing boat , the flying bridge may have controls permitting the ship to be piloted from the flying bridge, but will lack

608-401: The hull were protected by five layers of 1-inch (25 mm) wrought iron plates, backed by wood. The armor of the gun turret and the pilot house consisted of ten layers of one-inch plates. The ship's deck was protected by armor 1.5 inches (38 mm) thick. A 5-by-15-inch (130 by 380 mm) soft iron band was fitted around the base of the turret to prevent shells and fragments from jamming

672-454: The paddle wheel, the term bridge survived. Traditionally, commands would be passed from the senior officer on the bridge to stations dispersed throughout the ship, where physical control of the ship was exercised, as technology did not exist for the remote control of steering or machinery. Helm orders would be passed to an enclosed wheel house, where the coxswain or helmsman operated the ship's wheel . Engine commands would be relayed to

704-476: The ship a top speed of 8 knots (15 km/h; 9.2 mph). She carried 140–150 long tons (140–150 t) of coal. Ajax ' s main armament consisted of two smoothbore , muzzle-loading , 15-inch (381 mm) Dahlgren guns mounted in a single gun turret . Each gun weighed approximately 43,000 pounds (20,000 kg). They could fire a 350-pound (158.8 kg) shell up to a range of 2,100 yards (1,900 m) at an elevation of +7°. The exposed sides of

736-415: The ship could be commanded under fire. On a submarine, the bridge is the highest point on the conning tower , to provide for better visual navigation when on the surface. They became standard on United States Navy submarines after 1917, greatly improving the function of the vessels while at the surface. Modern advances in remote control equipment have seen progressive transfer of the actual control of

768-400: The ship to the bridge. The wheel and throttles can be operated directly from the bridge, controlling often-unmanned machinery spaces. Aboard modern warships, navigational command comes from the bridge, whereas electronically directed weapon systems are usually controlled from an interior compartment. On a commercial vessel, the bridge will contain the equipment necessary to safely navigate

800-538: The ship's completion was the addition of a hurricane deck between the turret and the funnel sometime after the end of the Civil War. The contract for construction of Ajax , originally named Manayunk , after a town in Pennsylvania , was signed by Snowden & Mason, on 15 September 1862. Her keel was laid down later in the year in Snowden & Mason's new shipyard at Pittsburgh , Pennsylvania. The ship's construction

832-616: The turret as had happened during the First Battle of Charleston Harbor in April 1863. The base of the funnel was protected to a height of 6 feet (1.8 m) by 8 inches (200 mm) of armor. A "rifle screen" of 1 ⁄ 2 -inch (13 mm) armor 3 feet (0.9 m) high was installed on the top of the turret to protected the crew against Confederate snipers based on a suggestion by Commander Tunis A. M. Craven , captain of her sister ship Tecumseh . The only known modification after

864-451: The turret. Other changes included deepening the hull by 18 inches (457 mm) to increase the ship's buoyancy, moving the position of the turret to balance the ship's trim and replacing all of the ship's deck armor. She was ready to be launched in April 1864, but the very low level of the Ohio River rendered that impossible. She was finally launched on 18 December. While fitting out , Ajax

896-483: Was again placed in reserve in 1891. The ship was on militia duty when the Spanish–American War began and she was recommissioned in 1898, to defend Baltimore , Maryland, although she was decommissioned later in the year before the necessary refit could be completed. Ajax was sold for scrap in 1899. Ajax was 235 ft (72 m) long overall , had a beam of 43 ft 8 in (13.31 m) and had

928-523: Was completed on 27 September 1865, although they drew enough water that they had to be anchored in the main channel where they were often struck by debris, drifting ice, and were vulnerable to accidents. This was a persistent problem and the Navy finally decided to move the ships down to New Orleans , in May 1866. The ship was renamed Ajax , on 15 June 1869. The monitor was briefly commissioned on 1 January 1871, under

960-420: Was delayed by multiple changes ordered while she was being built that reflected battle experience with earlier monitors. This included the rebuilding of the turrets and pilot houses to increase their armor thickness from 8 inches (203 mm) to 10 inches and to replace the bolts that secured their armor plates together with rivets to prevent them from being knocked loose by the shock of impact from shells striking

992-630: Was loaned to the New Jersey Naval Militia and moored at Camden , New Jersey. She was recommissioned for local defense duties on 9 July 1898, during the Spanish–American War in response to pressure from local politicians. The ship was intended for service at Baltimore, but she was decommissioned on 1 September 1898, before the necessary refit had been completed. Ajax was sold at the Philadelphia Navy Yard on 10 October 1899. Pilot house There are many terms for parts of

1024-431: Was ripped loose from her moorings on 5 March 1865, and she had to be towed back to her berth. The following day she was towed to Mound City , Illinois, where she arrived on 11 March. Snowden & Mason had to pay $ 7,000 for the tow as well as ship 400 long tons (410 t) of material needed to finish the ship. The monitor joined her sisters Oneota and Catawba in ordinary opposite Cairo , Illinois, when she
