Each of the four engine rooms has a pair of 1,250 kW Ship's Service Turbine Generators (SSTGs), providing the ship with a total non-emergency electrical power of 10,000 kW at 450 volts alternating current. Additionally, the vessels have a pair of 250 kW emergency diesel generators.[25] To allow battle-damaged electrical circuits to be repaired or bypassed, the lower decks of the ship have a Casualty Power System whose large 3-wire cables and wall outlets called "biscuits" can be used to reroute power.[67]
In addition to these search and navigational radars, the Iowa class were also outfitted with a variety of fire control radars for their gun systems. Beginning with their commissioning, the battleships made use of a pair of Mk 38 gun fire control systems with Mark 8 fire control radar to direct the 16-inch guns and a quartet of Mk 37 gun fire control systems with Mark 12 fire control radar and Mark 22 height finding radar to direct the 5-inch gun batteries. These systems were upgraded over time with the Mark 13 replacing the Mark 8 and the Mark 25 replacing the Mark 12/22, but they remained the cornerstones of the combat radar systems on the Iowa class during their careers.[69] The range estimation of these gunfire control systems provided a significant accuracy advantage over earlier ships with optical rangefinders; this was demonstrated off Truk Atoll on 16 February 1944, when the Iowa engaged the Japanese destroyer Nowaki at a range of 35,700 yards (32.6 km; 17.6 nmi) and straddled her, setting the record for the longest-ranged straddle in history.[37]
The citadel consisting of the magazines and engine rooms was protected by an STS outer hull plating 1.5 inches (38 mm) thick and a Class A armor belt 12.1 inches (307 mm) thick mounted on 0.875-inch (22.2 mm) STS backing plate; the armor belt is sloped at 19 degrees, equivalent to 17.3 in (439 mm) of vertical class B armor at 19,000 yards. The armor belt extends to the triple bottom, where the Class B lower portion tapers to 1.62 inches (41 mm). The ends of the armored citadel are closed by 11.3-inch (287 mm) vertical Class A transverse bulkheads for Iowa and New Jersey. The transverse bulkhead armor on Missouri and Wisconsin was increased to 14.5 inches (368 mm); this extra armor provided protection from raking fire directly ahead, which was considered more likely given the high speed of the Iowas. The deck armor consists of a 1.5-inch-thick (38 mm) STS weather deck, a combined 6-inch-thick (152 mm) Class B and STS main armor deck, and a 0.63-inch-thick (16 mm) STS splinter deck. Over the magazines, the splinter deck is replaced by a 1-inch (25 mm) STS third deck that separates the magazine from the main armored deck.[72] The powder magazine rooms are separated from the turret platforms by a pair of 1.5-inch STS annular bulkheads under the barbettes for flashback protection.[72] The installation of armor on the Iowas also differed from those of earlier battleships in that the armor was installed while the ships were still "on the way" rather than after the ships had been launched.[73]
Iowa was ordered 1 July 1939, laid down 27 June 1940, launched 27 August 1942, and commissioned 22 February 1943. She conducted a shakedown cruise in Chesapeake Bay before sailing to Naval Station Argentia, Newfoundland, to be ready in case the German battleship Tirpitz entered the Atlantic.[142] Transferred to the Pacific Fleet in 1944, Iowa made her combat debut in February and participated in the campaign for the Marshall Islands.[143] The ship later escorted US aircraft carriers conducting air raids in the Marianas campaign, and then was present at the Battle of Leyte Gulf.[143] During the Korean War, Iowa bombarded enemy targets at Songjin, Hŭngnam and Kojo, North Korea. Iowa returned to the US for operational and training exercises before being decommissioned on 24 February 1958.[144] Reactivated in the early 1980s, Iowa operated in the Atlantic Fleet, cruising in North American and European waters for most of the decade and participating in joint military exercises with European ships.[145] On 19 April 1989, 47 sailors were killed following an explosion in her No. 2 turret.[146] In 1990, Iowa was decommissioned for the last time and placed in the mothball fleet. She was stricken from the Naval Vessel Register on 17 March 2006. Iowa was anchored as part of the National Defense Reserve Fleet in Suisun Bay, California until October 2011, when she was towed from her mooring to Richmond, California for renovation as a museum ship. She was towed from Richmond in the San Francisco Bay on 26 May 2012, to San Pedro at the Los Angeles Waterfront to serve as a museum ship run by Pacific Battleship Center and opened to the public on 7 July 2012.
Missouri was the last of the four Iowas to be completed. She was ordered 12 June 1940, laid down 6 January 1941, launched 29 January 1944, and commissioned 11 June 1944. Missouri conducted her trials off New York with shakedown and battle practice in the Chesapeake Bay before transferring to the Pacific Fleet, where she screened US aircraft carriers involved in offensive operations against the Japanese before reporting to Okinawa to shell the island in advance of the planned landings. Following the bombardment of Okinawa, Missouri turned her attention to the Japanese homeland islands of Honshu and Hokkaido, performing shore bombardment and screening US carriers involved in combat operations. She became a symbol of the US Navy's victory in the Pacific when representatives of the Empire of Japan boarded the battleship to sign the documents of unconditional surrender to the Allied powers in September 1945. After World War II, Missouri conducted largely uneventful training and operational cruises until suffering a grounding accident. In 1950, she was dispatched to Korea in response to the outbreak of the Korean War. Missouri served two tours of duty in Korea providing shore bombardment. She was decommissioned in 1956. She spent many years at Puget Sound Naval Shipyard in Bremerton, Washington. Reactivated in 1984, as part of the 600-ship Navy plan, Missouri was sent on operational cruises until being assigned to Operation Earnest Will in 1988. In 1991, Missouri participated in Operation Desert Storm, firing 28 Tomahawk Missiles and 759 16-inch shells at Iraqi targets along the coast.[152] Decommissioned for the last time in 1992, Missouri was donated to the USS Missouri Memorial Association of Pearl Harbor, Hawaii, for use as a museum ship in 1999.[153]
Kentucky was ordered on 9 September 1940 and laid down on 7 March 1942. Work on the ship was suspended in June 1942, and the hull floated out to make room for the construction of LSTs.[162] The interruption lasted for two and a half years while a parallel aircraft carrier debate played out as with Illinois, reaching the same conclusion. Work resumed in December 1944, with completion projected for mid-1946. Further suggestions were made to convert Kentucky into a specialist anti-aircraft ship, and work was again suspended. With the hull approximately three-quarters completed, she was floated on 20 January 1950, to clear a dry dock for repairs to Missouri, which had run aground. During this period, plans were proposed to convert Kentucky into a guided missile battleship, which saw her reclassified from BB-66 to BBG-1.[163] When these failed construction of any sort, work never resumed and the ship was used as a parts hulk; in 1956, her bow was removed and shipped in one piece across Hampton Roads and grafted onto Wisconsin, which had collided with the destroyer Eaton.[155] In 1958, the engines installed on Kentucky were salvaged and installed on the Sacramento-class fast combat support ships Sacramento and Camden.[156] Ultimately, what remained of the hulk was sold for scrap on 31 October 1958.[144]
Recall that the mod recreates battles in Belgium and Luxembourg during the winter period from December 1944 to January 1945. To this end, dozens of new maps and units were prepared and gameplay mechanics were heavily rebalanced. On top of this, the level of realism of the virtual skirmishes has been significantly increased.
The feature was filmed in Ultra Panavision 70 and exhibited in 70 mm Cinerama. Unlike most World War II epics, it contains virtually no portrayals of actual senior Allied leaders, civilian or military. This is presumably because of controversies surrounding the battle, both during the war and after. Though Allied forces ultimately won the battle, the initial German counteroffensive caught them by surprise and caused high casualties. The film itself is completely made up, and doesn't really match any of the actual Battle of the Bulge moments in December 1944 though January 1945, with the sole exception of the Malmedy Massacre. None of which prevented the film from being frequently aired on American television, especially in The '70s.
After America entered the war in late 1941, Eisenhower showed his prowess as a military leader by overseeing Allied military operations in North Africa, Sicily, and Italy in 1942-43, and during the Allied invasion of Western Europe beginning in June 1944. By the time of the great German offensive through the Ardennes in December 1944 that created a large salient, or bulge, in the Allied lines, Eisenhower commanded the Allied forces in the European Theater of Operations as a five-star general. The resulting Battle of the Bulge gave Eisenhower a chance to demonstrate his knowledge of tank warfare and the doctrine of how best to contain and reduce an enemy salient. Army service schools during the period between the World Wars had taught that the shoulders of a salient must be firmly held before its reduction by counterattack.
