Sikorsky SH-3 Sea King and Boeing AH-64 Apache

The Sikorsky SH-3 Sea King is the American twin-engined anti-submarine warfare helicopter. (ASW). It was built by the Sikorsky Aircraft. It is the first ASW Helicopter and it has turbo shaft engines. And, it is also the world's first amphibious helicopter. It was introduced in 1961 and it's been serving the United States Navy since then.
It can presently be built by Italy and Japan (Under license) and by United Kingdom.

Origins :

During the cold war, the Soviet navy decided to construct a fleet of over 200 submarines.
The United States Navy decided to counter this threat by developing the ASW technologies. Thus came the Sea King.  On 5th of February, 1962 with the HSS-2 Sea King, the United States set an absolute helicopter speed record of around 210.6 mph. This record was broken by the SUD Super Frelon helicopter on 23rd of July, 1963 setting a record of 217.7 mph.

I'd say, The Sikorsky SH-3 Sea King is the KING OF THE SEA! It's the best ASW Helicopter. Best for the Sea's!

Boeing Ah-64 Apache : 

The Boeing AH-64 Apache is a four-blade, twin-engine attack helicopter with a tailwheel-type landing gear arrangement and a tandem cockpit for two-man crew. The Boeing AH-64 was introduced into the U.S. Army service in April 1986.The Apache features a nose-mounted sensor suite for target acquisition and night vision systems. It's armed with a 30-millimeter M230 Chain Gun carried between the main landing hear under the aircraft's forward fuselage. It carries a mixture of AGM-114 Hellfire missiles and Hydra-70 Rocketpods.


The AH-64D Apache Longdow, an upgraded version of the original Apache was delivered to the Army in March, 1997. Around a 1000 AH-64's have been produced to the date.

The US Army is the primary operator of the AH-64 but tt's also used in Greece, Japan, Israel, Neterlands and Singapore aswellas being produced under license in the United Kingdom and the AgustaWestland Apache.


The AH-64 is adaptable to numerous different roles within its context as Close Combat Attack (CCA). 

In the late 1980's, the Stinger and AIM-9 Sidewinder air-to-air missiles and the AGM-122 Sidearm anti-radiation missile were evaluated for use upon the AH-64.
