Iwo Jima-class amphibious assault ship

The Iwo Jima-class amphibious assault ships of the United States Navy were the first amphibious assault ships designed and built as dedicated helicopter carriers, capable of operating up to 20 helicopters to carry up to 1,800 marines ashore.[1] They were named for battles featuring the United States Marine Corps, starting with the Battle of Iwo Jima. The first ship of the class was commissioned in 1961, and the last was decommissioned in 2002. The hull classification of "LPH" stands for "Landing Platform Helicopter".

USS Iwo Jima (LPH-2), the lead ship of the class, off the coast of South Vietnam in 1965.

Operational history edit

Ships of this class participated in several conflicts and peacekeeping and humanitarian relief operations:

One ship of this class, USS Guam (LPH-9), was used in a 1970-1974 Sea Control Ship experiment to test the concept of a smaller aircraft carrier using V/STOL aircraft.

Another ship, USS Inchon (LPH-12), was converted to a mine countermeasures ship which hosted mine sweeping helicopters.

The hull design of the Iwo Jima-class also became the basis of the slightly larger Blue Ridge class of amphibious command ships.[2]

The seven ships of the Iwo Jima-class were given non-sequential hull numbers, as, at the time of their construction, five existing aircraft carriers were being converted to serve in the Landing Platform Helicopter role - these five ships were renumbered, with the new ships slotted into a single sequence. The five existing ships were:

Name Previous hull number New hull number
Block Island
CVE-106
LPH-1a
Boxer
CV-21
LPH-4
Princeton
CV-37
LPH-5
Thetis Bay
CVE-90
LPH-6
Valley Forge
CV-45
LPH-8
  • ^a Block Island was redesignated from CVE-106 to LPH-1 in anticipation of the ship being converted into the LPH role under project SCB 159. However, before the work could begin, the ship's conversion was cancelled, and it reverted back to its original number.[3]

Popular culture edit

One of the Iwo Jima-class ships served as the fieldsite in Edwin Hutchins's classic cognitive science study Cognition in the Wild.[4] Although Hutchins does not mention the ship class by name, on p. 7 he characterizes it as a 603-foot-long (184 m) amphibious helicopter carrier.
