The Invention of Aircraft Carrier
The Invention of the Aircraft Carrier was a great event in U.S.
Maritime history. The Aircraft Carrier battle group has become a critical
element of United States foreign policy and acts as the central force in the
nation’s forward deployed presence around the globe. The Aircraft Carrier is
of great strategical importance around the world. Aircraft Carriers provide a
wide range of possible response for the National Command Authority. The
Carrier’s mission is to provide a credible , sustainable, independent forward
presence and conventional deterrence in peacetime, To operate as the
cornerstone of joint/allied maritime expeditionary forces in times of crisis,
and to operate and support aircraft attacks on enemies, protect friendly forces
and engage in sustained independent operations in war.
Aircraft Carriers are deployed worldwide in support of U.S. interests
and commitments. They can respond to global crises in ways ranging from
peacetime presence to full-scale war. Together with their on-board air wings,
the carriers have vital roles across the full spectrum of conflict. Since the
Earth is covered by 70% water, the Aircraft Carrier does not need to make a
base in foreign countries. All it needs is one land base, this is true because

when the Carrier is out to sea and needs fuel, a fuel-ship will come along and
refuel it. This is a huge advantage over air fields.
The Aircraft Carrier is a ship with a long, unobstructed flight deck that
permits takeoffs and landings by high-performance airplanes. A carrier is in
effect a mobile air base. Planes are stored below deck and brought up and
down on elevators. They take off under their own power or may be launched
by catapults, which are explained in the next paragraph. Decks are angled so
that pilots missing the arresting gear will be able to go around again without
hitting other aircraft. Carriers, equipped with or capable of carrying missiles,
are the heart of modern striking forces, accompanied by a variety of support
vessels: destroyers and cruisers for protection and supply ships bearing fuel,
ammunition, and food. The following few paragraphs will be telling you
about the parts of the Aircraft Carrier and its uses.
Each carrier-based aircraft has a tailhook, a hook bolted to an 8-foot
bar extending from the after part of the aircraft. It is with the tailhook that the
pilot catches one of the four steel cables stretched across the deck, bringing
the plane, traveling at 150 miles per hour, to a complete stop in about 320
feet. The cables are set to stop each aircraft at the same place on the deck,
regardless of the size or weight of the plane. There are also the Catapults that
launch the planes off of the ship. The four steam-powered catapults thrust a
48,000 Pound aircraft 300 feet, from zero to 165 miles per hour in 2 seconds!
On each plane’s nose gear is a T-bar which locks into the catapult’s shuttle
which pulls the plane down the catapult. The flight deck crew can launch 2
aircraft and land one every 37 seconds in daylight, and one per minute at
night.
The Bridge is the Primary control position for every ship when the ship
is underway, and the place where all orders and commands affecting the ship,
her movements, and routine originate.
The earliest flight from a ship was made off an improvised platform on
the U.S. cruiser Birmingham in 1910. The first true carrier designed to permit

takeoffs and landings was the British merchant ship HMS Argus, completed
in 1918. The first U.S. carrier, the Langley, a converted collier, joined the
fleet in 1922, and in 1927 the Lexington and Saratoga were converted from
battle cruisers.
After World War I, major carrier fleets were built by the United States,
Japan, and Britain; in the 1930s tactical exercises were held by the U.S. Navy
to study and improve efficiency of its carrier operations. By World War II,
however, Japan’s carrier fleet was numerically and qualitatively superior to
the American and British fleets in the Pacific. The use of six aircraft carriers
by Japan to attack Pearl Harbor on December 7, 1941, opened the war in the
Pacific. No American carriers were present during the attack. The major
carrier battle of Midway of June 3-6, 1942, cost the Japanese four carriers;
America lost one, the Yorktown. This victory gained the U.S. mastery of the
skies and of the seas and turned the tide of the war. By 1944 the Japanese
navy had been destroyed primarily by carrier-based aircraft assault, in
addition to submarine action. In the European theater, England used carriers
in support of operations in Norway and for convoy support in the Atlantic
and Mediterranean. Carriers were also part of the British Eastern Fleet.
Since World War II, carriers have been designated by size and mission
All the present U.S. fleet is of the attack class, with capabilities for
conversion to use as submarine warfare, utility, and assault helicopter aircraft
carriers. They bear the classification symbols CV or CVN, the N denoting a
carrier propelled by nuclear energy.
In 1989 the U.S. was the world’s principal user of carriers, with a fleet
of 15 and 2 under construction. Two carriers were of the old Midway class,
completed shortly after World War II, and eight were built in the 1950s and
’60s. Five others were nuclear powered. One of these, the Nimitz, which are
the largest warships in the world have the following traits: a 4.5 acre deck, 2
nuclear reactors, four geared steam turbines, four shafts. The length is 1,040

feet(317 meters).
The beam is 134 feet(40.34 meters) The displacement is
97,000 tons when fully loaded(87.998 metric tons).
The speed is 30+
knots(34.5 miles per hour).
It can hold approximately 85 aircraft. It has a
crew of 3,300 for the ship’s company and a crew of about 3,000 for the Air
Wing. The armament is four NATO Sea Sparrow missile launchers, 20 mm
Phalanx CIWS mounts, and other armaments that are classified. The ship
costs about $4.5 billion each.
The sonar system is the hull-mounted Type 2016 active/passive search
and attack sonar by Thomson Marconi Sonar. The ship’s radar systems
include: GEC-Marconi Type 909 G/H-band fire control radar, housed in the
large radomes at the forward and aft ends of the island structure.
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
The Essay on Ship And Larger Merchant Ships
A research vessel (RV or R/V) is a ship designed and equipped to carry out research at sea. Research vessels carry out a number of roles. Some of these roles can be combined into a single vessel, others require a dedicated vessel. Due to the demanding nature of the work, research vessels are often constructed around an icebreaker hull, allowing them to operate in polar waters. DREDGER The Geopotes ...
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.)
The British fleet included three carriers, designed for antisubmarine
warfare and command control missions. France had two carriers, built in the
1950s and a nuclear-powered 36,000-ton carrier under construction, all with
antisubmarine warfare, helicopter, and command control functions. Two light
carriers were maintained by the Navies of India and Spain, and one each by
Argentina and Brazil. Most of these Carriers were acquired from larger
powers.
The invention of the Aircraft Carrier has immensely influenced the
USA’s freedoms. The lasting historical impact of the Aircraft Carrier is huge.
The use of the Aircraft Carrier is so large because of the amount of sea that it
is able to use and the use that it has. It can be used a great deal especially
when considering that the Earth is covered by more than 70% water. The
invention of the Aircraft Carrier plays a major role in keeping the world safe
from democracy. The invention of the Aircraft Carrier has played a great role
in the United States of America’s freedoms.
