341st Missile Wing Heritage Pamphlet 2018

Malmstrom AFB · 30 pages · text from the file's own layer

This heritage pamphlet from Malmstrom AFB traces the history of the 341st Missile Wing. The unit began as a B-25 bomb group in the China-Burma-India Theater in 1942, then flew B-47s at Abilene AFB before being activated at Malmstrom in July 1961. The pamphlet covers the Minuteman I, II and III deployments, the Cuban Missile Crisis alert, arms-reduction work under START, trophies, wing commanders and a missile field chronology. It also has museum display notes on missiles and the UH-1 helicopter.

341st Missile Wing History
Minuteman II
First Minuteman II at Cape Canaveral
Even as the Minuteman I program raced forward, the Air Force began developing the new
Minuteman II. The new missile was a significant improvement over its predecessor. A new
second-stage motor with a single nozzle and a secondary liquid injection for thrust vector control
increased the missile's range from 6,300 to 7,000 miles. The new motors also enabled the
Minuteman to carry the larger W-56 warhead with a yield of 1.2 megatons. An improved
guidance system made the missile more accurate, and it could store a larger number of
preprogrammed targets within its internal memory. Moreover, Minuteman II also carried
penetration aids to camouflage the reentry vehicle during reentry.
The Air Force awarded Boeing the Minuteman II contract in March 1962 and the Seattle-based
contractor conducted the first test flight in September 1964.
The Minuteman II was a tremendous improvement over Minuteman I. Although the new ICBM
was only 2 feet taller and 8,000 pounds heavier than its predecessor, a new second-stage engine
extended the missile's range from 6,300 to 7,000 miles and increased the payload to enable it to
carry a 1.2-megaton warhead. Minuteman II was also equipped with a new Autonetics guidance
system that narrowed the circular error probable (CEP) to 1.5 miles at maximum range. The Air
Force calculated that Minuteman II's greater range, larger warhead, and improved accuracy gave
it eight times the "kill" capability of Minuteman I.
In May 1966 SAC placed its first Minuteman II squadron on operational alert, and by April 1967
accepted its 200th Minuteman II. At that point the Minuteman force stood at 1,000 missiles; 800
Minuteman Is and 200 Minuteman IIs. Continuing its missile modernization effort, throughout
the late 1960s the Air Force replaced many of its Minuteman Is with Minuteman IIs, and by May
1969 it had 500 Minuteman Is and an equal number of Minuteman 11s on operational alert.
Minuteman II Major Features
Performance improvements realized in Minuteman II include greater range, increased throw
weight, improved accuracy and reliability, multiple target selection, and greater penetration
