Реферат: The Invention Of The Aircraft Carrier Essay
Siemens Plessey Type 996 surface search radar antennae mounted very high
on the tower between the two funnels. HMS Ark Royal has GEC-Marconi
Type 992. Both radars operate at E and F-bands.
The GEC-Marconi Type 1022 air search radar operates in D-band.
The HMS Invincible and Ark Royal are equipped with the Kelvin Hughes
Type 1006 navigation radar and HMS Illustrious has the Type 1007, both
operating at l-band.
The first class of Invincible Aircraft Carrier was built by Vickers
Shipbuilding and Engineering at Barrow-in-Furness. The ship was launched
in may 1977 and commissioned in July 1980. The Invincible class Aircraft
Carrier is armed with three Mark 15 Phalanx (CIWS) missile systems. Each
Phalanx CIWS has one 20 mm M61A1 Vulcan Gatling-principle gun which
fires 3,000 rounds per minute at a range of 1.5 km. The HMS Invincible and
Illustrious each have three Signal Goalkeeper CIWS, one of which is installed
in the forward gun platform at the bow of the ship. The other two are on the
island and on the lower gun deck gun platform at the stern. Goalkeeper’s
Gatling principle 30 mm gun provides a maximum firing rate of 1000 rounds
per minute. The Invincible class is fitted with the type 675(2) jamming
system which is an effective form of countermeasures. The ship’s decoy
systems consist of eight 130 mm six-barrel launchers that produce the Sea
Gnat chaff and infra-red decoys.
By the late 1980s the Soviet Navy had four Kyyiv carriers, plus two
nuclear carriers under construction. The Kyyiv carriers were 274 m (899 ft.)
long, displacing 38,000 tons. This class appeared to be designed for
antisubmarine warfare and was equipped with helicopter and possible
vertical-takeoff-and-landing (VTOL) aircraft. The two nuclear-powered
carriers are 75,000-ton attack vessels. (In 1991 the Soviet Navy became part
of the armed forces of the Commonwealth of Independent States, but control
of the Black Sea fleet was in dispute between Russia and Ukraine.)
