Aircraft Carriers
 USS Ronald
Reagan
An aircraft carrier is a warship designed to deploy and in most
cases recover aircraft, acting as a sea-going airbase. Aircraft carriers thus
allow a naval force to project air power great distances without having to
depend on local bases for staging aircraft operations. They have evolved from
wooden vessels used to deploy a balloon into nuclear powered warships that
carry dozens of fixed and rotary wing aircraft.
Balloon carriers were the first ships to deploy manned aircraft,
used during the 19th and early 20th century, mainly for observation purposes.
The 1903 advent of fixed wing airplanes was followed in 1910 by the first
flight of such an aircraft from the deck of a US Navy cruiser. Seaplanes and
seaplane tender support ships, such as HMS Engadine, followed. The development
of flat top vessels produced the first large fleet ships. This evolution was
well underway by the mid 1920s, resulting in ships such as the HMS Hermes,
Ho-sho-, and the Lexington class aircraft carriers.
World War II saw the first large scale use and further
refinement of the aircraft carrier, spawning several types. Escort aircraft
carriers, such as USS Barnes, were built only during World War II. Although
some were purpose built, most were converted from merchant ships, and were a
stop-gap measure in order to provide air support for convoys and amphibious
invasions. Light aircraft carriers, such as USS Independence represented a
larger, more "militarized" version of the escort carrier concept. Although the
light carriers usually carried the same size air groups as escort carriers,
they had the advantage of higher speed as they had been converted from cruisers
under construction rather than civilian merchant ships.
Wartime emergencies also saw the creation or conversion of
other, unconventional aircraft carriers. CAM ships, like the SS Michael E, were
cargo carrying merchant ships which could launch but not retrieve fighter
aircraft from a catapult. These vessels were an emergency measure during World
War II as were Merchant aircraft carriers (MACs), such as MV Empire MacAlpine,
another emergency measure which saw cargo-carrying merchant ships equipped with
flight decks. Battlecarriers were created by the Imperial Japanese Navy to
partially compensate for the loss of carrier strength at Midway. Two of them
were made from Ise class battleships during late 1943. The aft turrets were
removed and replaced with a hangar, deck and catapult. The heavy cruiser Mogami
concurrently received a similar conversion. This "half and half" design was an
unsuccessful compromise, being neither one thing nor the other. In addition the
superstructure and the turbulent airflow it generated made landing even more
hazardous than usual. Submarine aircraft carriers, such as the French Surcouf,
or the Japanese I-400 class submarines which were capable of carrying 3 Aichi
M6A Seiran aircraft. The first of these were built in the 1920s, but were
generally unsuccessful at war. Modern navies that operate such ships treat
aircraft carriers as the capital ship of the fleet, a role previously played by
the battleship. The change, part of the growth of air power as a significant
part of warfare, took place during World War II. This change was driven by the
superior range, flexibility and effectiveness of carrier-launched aircraft.
Following the war, the scope of carrier operations continued to
increase in size and importance. The Supercarrier, typically displacing 75,000
tonnes or greater has been the pinnacle of carrier development since their
introduction. Most are powered by nuclear reactors and form the core of a fleet
designed to operate far from home. Amphibious assault carriers, such as USS
Tarawa or HMS Ocean, which serve the purpose of carrying and landing Marines
and operate a large contingent of helicopters for that purpose. They have a
secondary capability to operate VSTOL aircraft. Also known as "commando
carriers" or "helicopter carriers".
Lacking the firepower of other warships, carriers by themselves
are considered vulnerable to attack by other ships, aircraft, submarines or
missiles and therefore travel as part of a carrier battle group (CVBG) for
their protection. Unlike other types of capital ships in the 20th century,
aircraft carrier designs since World War II have been effectively unlimited by
any consideration save budgetary, and the ships have increased in size to
handle the larger aircraft: The large, modern Nimitz class of United States
Navy carriers has a displacement nearly four times that of the World War II-era
USS Enterprise yet its complement of aircraft is roughly the same, a
consequence of the steadily increasing size of military aircraft over the
years. From Wikipedia
Battleships
A battleship is a large, heavily-armored warship
with a main battery consisting of the largest caliber of guns. They are larger,
better-armed and better-armored than cruisers.
Battleships have evolved a great deal over time, as designs
continually adapt technological advances to maintain an edge. The word
battleship was coined around 1794 and is a shortened form of line of battle
ship, the dominant warship in the Age of Sail. The term came into formal use in
the late 1880s to describe a developed type of ironclad warship, and by the
1890s design had become relatively standard on what is now known as the
pre-Dreadnought battleship. In 1906, HMS Dreadnought heralded a revolution in
battleship design, and for many years modern battleships were referred to as
dreadnoughts.
As much as a type of war vessel, battleships constituted a
potent symbol of national might and naval domination. For decades, the numbers
and abilities of battleships were a major factor in diplomacy and military
strategy. The global arms race in battleship construction in the early 1900s
was a significant factor in the origins of World War I, which saw a clash of
huge battlefleets at the Battle of Jutland. The construction of battleships was
limited by the Naval Treaties of the 1920s and 1930s, but battleships both old
and new were deployed during World War II.
Despite this record, some historians and naval theorists
question the value of the battleship. Aside from Jutland, there were few great
battleship clashes. And despite their great firepower and protection,
battleships remained vulnerable to much smaller, cheaper ordnance and craft:
initially the torpedo and mine, and later aircraft and the guided missile. The
growing range of engagement led to the battleship's replacement as the leading
type of warship by the aircraft carrier during World War II, being retained
into the Cold War only by the United States Navy for fire support purposes.
These last battleships were removed from the U.S. Naval Vessel Register in
March 2006.
With the decommissioning of the last Iowas, no battleships
remain in service (including in reserve) with any navy worldwide. A number are
preserved as museum ships, either afloat or in dry-dock. The USA has a large
number of battleships on display. USS Massachusetts, North Carolina, Alabama,
New Jersey, Wisconsin, Missouri, and Texas. Missouri, and New Jersey are now
museums at Pearl Harbor and Camden, N.J. respectively. Wisconsin is a museum
(at Norfolk, Va.), and was recently removed from the Naval Vessel Register.
However, pending donation, the public can still only tour the deck, since the
rest of the ship is closed off for dehumidification. The only other true
battleship on display is the Japanese pre-Dreadnought Mikasa. A number of
ironclads and ships-of-the-line are also preserved, including HMS Victory,
Warrior, the Swedish Vasa, the Dutch Buffel and Schorpioen, and the Chilean war
trophy, Huáscar. The earliest ancestor of the battleship still on
display is the sixteenth-century English war vessel Mary Rose. From
