The Arleigh Burke class represents a return to
all-steel construction and incorporates electromagnetic
pulse hardening, enhanced firefighting features, and a
collective protection system to provide protection
against nuclear, chemical, or biological contamination.
This vital equipment is distributed through the ship,
giving the ship improved blast and fragmentation
protection, which lets them to survive a hit and continue
Frigates.The classification frigate designates
ships used for open-ocean escort and patrol. Frigates
resemble destroyers in appearance, but they are slower,
have only a single screw, and carry less armament.
Frigates are slowly being replaced by DDGs. The Oliver
Hazard Perry class is the only class of guided-missile
frigates still commissioned. The USS Ingraham
(FFG 61) (fig. 8-20) carries the following armament:
A single 76-mm, .62-caliber
A 20-mm Vulcan/Phalanx rapid-fire gun
A single launcher for Harpoon missiles
Two SH-60 LAMPS III helicopters
Two Mk 46 triple-torpedo tubes
Submarines.The Navy deploys two classes of
submarines attack submarines (SSNs) and ballistic
missile submarines (SSBNs). The mission of nuclear
attack submarines (SSNs) is to locate and destroy
enemy ships and submarines. They also act as scouts,
deliver supplies and personnel to locations in enemy
territory, and perform rescue missions.
Fleet ballistic missile submarines (SSBNs) deliver
ballistic missile attacks against assigned targets from
either a submerged or surfaced condition. Most of the
SSBNs are being converted to carry Trident missiles,
which have greater range and multiple warheads.
A new class of submarine, the Ohio class (fig. 8-21),
has been developed for the Trident missile. The Ohio
class is the largest undersea craft developed by the
Navy. It displaces 16,600 to 18,700 tons. The size of the
Trident submarine is dictated by the larger size missile
required for ranges of 4,000 to 6,000 miles and by the
larger reactor plant required to drive the ship. The
submarine has 24 tubes for the Trident missile and 4
torpedo tubes located in the bow.
A nuclear-powered attack submarine, like that of
the Sturgeon class, displaces 3,800 to 4,700 tons, can do
more than 20 knots, and has four torpedo tubes. The
newer Seawolf class fast-attack submarine displaces
about 9,137 tons, has four torpedo tubes, and can attain
speeds of over 35 knots (fig. 8-22). The Seawolf
performs a variety of crucial assignments, from
underneath the Arctic icepack to all regions anywhere in
the world. Its missions include surveillance,
intelligence collection, special warfare, covert
cruise-missile strike, mine warfare, and anti-submarine
and anti-surface ship warfare. The Seawolfs stealth
characteristics make it the worlds quietest submarine.
Early submarines were named after marine life. The
first SSBNs, however, were given names of persons well
known in American history, like USS George
Washington, USS Patrick Henry, and USS Lafayette.
The new fast-attack submarines (SSNs) are named
after American cities, like the USS Los Angeles,
USSAlbuquerque, and USS Memphis. The Tridents
(SSBNs) are being named after American states, like
the USS Ohio and USS Michigan.

classified as combatants are amphibious warfare ships
and mine warfare ships.
Amphibious warfare ships.An amphibious
assault operation is the fastest means of landing large
numbers of personnel, equipment, and supplies on
enemy-held territory. The lessons learned during World
War II, Korea, and Vietnam have resulted in the U.S.
Navy having the largest and most capable amphibious
force in the world. With the introduction of new classes
of ships and new types of landing craft and helicopters,
the U.S. Navy can conduct an amphibious operation
almost anywhere in the world.

amphibious assault ships (LHAs) are able to embark,
deploy, and land a marine battalion landing team by
helicopter, landing craft, amphibious vehicle, or by a
combination of these methods. The Tarawa-class ships
have 9 Sea Stallions and 12 Sea Knight helicopters plus
6 Harrier attack planes. It also carries 2 RAM
