Raytheon and Lockheed Martin Missiles and Fire Control developed the Griffin as a low-cost modular system, using components from earlier projects, including the FGM-148 Javelin and the AIM-9X Sidewinder.
It was originally designed to be launched from the US Special Operations Command's MC-130W Dragon Spear gunship and can be guided either by a semi-active laser seeker or with GPS.
[5] Weighing 33 lb (15 kg) and measuring 3.6 ft (1.1 m) in length, it is launched from a 10-tube "Gunslinger" launcher that fits on the rear ramp of a Marine KC-130 tanker/transport or both the US Air Force AC-130W "Stinger II"[6] and AC-130J "Ghostrider"[7] gunship variants.
Griffin Block II B is a short-range, rocket-powered air-to-surface or surface-to-surface missile that can be fired from UAVs as well as helicopters, attack aircraft, U.S. Air Force AC-130W gunships,[6] and Marine Corps KC-130J tankers.
The U.S. Navy has tested the Griffin as a shipboard missile guided by laser at fast-moving small boats; they planned to use it on the Littoral Combat Ships.
The Block III includes an improved semi-active laser seeker with better electronics and signal processing and a new Multi-Effects Warhead System to maximize lethality against different targets.
[14] The MK-60 Patrol Coastal Griffin Missile System achieved initial operational capability (IOC) with the U.S. Navy in March 2014, which is intended to provide protection for vessels in littoral areas against swarm boat attacks and other threats.
[16][17] In tests, the Sea Griffin's new imaging infrared (IIR) seeker has streamed video back to operators through the data-link to provide verification before the missile strikes the target.
