BGM-109G Gryphon

The BGM-109G was developed as a counter to the mobile MRBM and IRBM nuclear missiles (SS-20 Saber) deployed by the Soviet Union in Eastern Bloc European countries.

[citation needed] Since the U.S. deployed only one modern cruise missile in the tactical role, the GLCM name stuck.

A conventionally configured cruise missile, the BGM-109 was essentially a small, pilotless flying machine, powered by a turbofan engine.

The trade-off for this low-observability flight is strike time; cruise missiles travel far more slowly than a ballistic weapon, and the GLCM was typical in this regard.

[1] Militarily, the GLCM was targeted against fixed targets—at the outer edge of its range, the missile's flight time with its subsonic turbofan was more than 2+1⁄2 hours.

Flying at a low level, the missile was guided by TERCOM (terrain contour matching) to the target.

Each TEL and LCC was towed by a large MAN KAT1 8x8 tractor and was capable of traversing rough terrain.

Aside from presenting a course of action to NATO commanders in the event of war, it put the Kremlin leaders (in range of the GLCM and possibly the Pershing, even in Moscow) in a position of fearing a decapitating NATO first strike, which could have moved them toward a launch on warning policy as the only way to maintain mutually assured destruction.

Golf and Hotel class SSBNs armed with R-27 Zyb and SS-N-5s) available during this time, so any fears of a decapitating first strike were not necessarily justified.

[7] Despite initial fears of greater instability, the deployment of GLCM ultimately caused Soviet leaders to enter into negotiations for, and finally, sign off on, the INF treaty.

The recognition by Soviet leaders of the threat posed by the GLCM and Pershing II missiles made them far more inclined to agree to negotiate their own intermediate-range weapons, especially the SS-20, out of service, in exchange for the elimination of the threat posed by the GLCM and the Pershing II.

[9] GLCM was removed from Europe beginning in 1988, and over the next three and a half years all units were transported to Davis Monthan AFB and destroyed or converted into displays by 1991.

[10] President Donald Trump announced on 20 October 2018 that he was withdrawing the U.S. from the INF treaty, citing Russian non-compliance.

GAMAs at RAF Molesworth , England. 4 GAMAs, 1 per flight, each holding 16 missiles, a total 64 missiles. Molesworth was completely reconstructed between 1981 and 1985, being transformed from a largely abandoned World War II Eighth Air Force B-17 base to a modern NATO facility. The large World War II "J" type hangar in the upper left was retained as a memorial to the World War II 303d Bombardment Group. Both Bob Hope and Glenn Miller performed USO shows in that hangar during the war years.
