The MGM-134A Midgetman, also known as the Small Intercontinental Ballistic Missile,[1] was an intercontinental ballistic missile developed by the United States Air Force. The system was mobile and could be set up rapidly, allowing it to move to a new firing location after learning of an enemy missile launch. To attack the weapon, the enemy would have to blanket the area around its last known location with multiple warheads, using up a large percentage of their force for limited gains and no guarantee that all of the missiles would be destroyed. In such a scenario, the U.S. would retain enough of their forces for a successful counterstrike, thereby maintaining deterrence.
Overview
The Midgetman grew out of a requirement expressed in the mid-1980s by the
System definition studies for the Small Intercontinental Ballistic Missile commenced in 1984 under an Air Force Program Office located at
Design
In design the XMGM-134A was a three-stage
The Midgetman had a range of some 11,000 kilometers (6,800 mi). Two warheads were developed for the missile: the W87-1 warhead in a Mark 21 re-entry vehicle with a yield of 475 kt (1,990 TJ), and the W61 earth penetrating warhead with a yield of 340 kt (1,400 TJ).[3][4]
Carrier vehicle: Hard Mobile Launcher
The Midgetman was to be carried by an eight-wheel drive Hard Mobile Launcher (HML) vehicle. Most of these vehicles would normally remain on bases, only being deployed in times of international crisis when nuclear war was considered more likely. The Hard Mobile Launcher was radiation hardened and had a trailer mounted plow to dig the HML into the earth for additional nuclear blast protection.[5]
Cancellation

The Soviet equivalent of this missile was the RSS-40 Kuryer which was tested but cancelled in October 1991. This could have filled the role of the more cost effective

An unarmed Midgetman missile tumbled off course and was destroyed over the Pacific Ocean today about 70 seconds after the Air Force launched the first test flight of the new weapon, which has been at the center of a political struggle between Congress and the Pentagon.

It achieved its first totally successful flight test on 18 April 1991, when a SICBM that had been cold-launched from a canister at Vandenberg AFB reached its target in the Kwajalein Test Range.

The B61-7 laydown bomb also served as the basis for the W61 program in the late 1980s and early 1990s, an effort to equip a small intercontinental ballistic missile (Midgetman) with a strategic earth-penetrating warhead. Engineering authorization was granted for the W61 in 1990, only to be canceled 18 months later when the George H.W. Bush administration discontinued the Midgetman as the Cold War wound down.

This vehicle was the last engineering model, or Engineering Test Unit (ETU), of a mobile, raditional-hardened, truck launcher designed to carry and launch the MGM-134A Small Intercontinental Ballistic Missile (unofficially known as "Midgetman"). [...] The vehicle is capable of using the trailer-mounted plow to dig the launcher into the earth for additional protection from a nuclear blast.
