Sorry but the american design was always more advanced and sophisticated.Back in the 50 and 60s while Russia was relying and stockpiling for the kill
ratio and having less accurate systems.I would believe the mx also would have been the most advanced.
The Peacekeeper missile is America's newest intercontinental ballistic missile. With the end of the Cold War, the US has begun to revise its
strategic policy, and has agreed to eliminate the multiple re-entry vehicle Peacekeeper ICBMs by the year 2003 as part of the Strategic Arms Reduction
Treaty II. The Peacekeeper (designated LGM-118A) is a four-stage intercontinental ballistic missile capable of carrying up to ten
independently-targetable reentry vehicles with greater accuracy than any other ballistic missile. Its design combines advanced technology in fuels,
guidance, nozzle design, and motor construction with protection against the hostile nuclear environment associated with land-based systems. The
Peacekeeper is much larger than Minuteman, over 70 feet long and weighing 198,000 pounds. It is a four stage missile like the Minuteman III, with the
first three stages being solid propellant and the fourth stage bu hypergolicly fueled with hydrazine and nitrogen tetroxide. Although capable of
carrying eleven Mark 21 RVs, treaty limits mandated deploying the Peacekeeper with only ten RVs. The entire missile is encased in a canister in the
silo to protect it against damage and to permit "cold launch". The Minuteman II and III ignite their first stage engines while in the LF, but the
Peacekeeper is ejected by pressurized gas some fifty feet into the air before first stage ignition.
The Peacekeeper is a three-stage rocket ICBM system consisting of three major sections: the boost system, the post-boost vehicle system and the
The boost system consists of three rocket stages that launch the missile into space. These rocket stages are mounted atop one another and fire
successively. Three of the four stages exhausted their solid propellants through a single adjustable nozzle which guided the missile along its flight
path. Motorcases made of kevlar epoxy material held the solid propellants. The fourth stage post-boost vehicle employed a liquid bi- propellant rocket
propulsion system to provide velocity and attitude correction for missile guidance. The post-boost vehicle also employed a self-contained inertial
navigation system that allowed the missile to operate independent of ground reference or commands during flight.
The 28-foot first-stage solid-fuel rocket motor weighed approximately 108,000 pounds and is capable of boosting the missile to about 75,000 feet. The
18-foot long second-stage motor propelled the missile to an altitude of about 190,000 feet and weighed 60,000 pounds. The rocket motor in the
eight-foot third stage weighed 17,000 pounds and supplied the thrust to boost the missile to about 700,000 feet. The 2,300 pound post-boost fourth
stage vehicle was designed to maneuver the missile into position for the multiple reentry vehicles to deploy in their respective ballistic
Following the burnout and separation of the boost system's third rocket stage, the post-boost vehicle system, in space, maneuvers the missile as its
re-entry vehicles are deployed in sequence.
The post-boost vehicle system is made up of a maneuvering rocket, and a guidance and control system. The vehicle rides atop the boost system, weighs
about 3,000 pounds (1,363 kilograms) and is 4 feet (1.21 meters) long.
The top section of the Peacekeeper is the re-entry system. It consists of the deployment module, up to 10 cone-shaped re-entry vehicles and a
protective shroud. The shroud protects the re-entry vehicles during ascent. It is topped with a nose cap, containing a rocket motor to separate it
from the deployment module.
The deployment module provides structural support for the re-entry vehicles and carries the electronics needed to activate and deploy them. The
vehicles are covered with material to protect them during re-entry through the atmosphere to their targets and are mechanically attached to the
deployment module. The attachments are unlatched by gas pressure from an explosive cartridge broken by small, exploding bolts, which free the re-entry
vehicles, allowing them to separate from the deployment module with minimum disturbance. Each deployed re-entry vehicle follows a ballistic path to
The Peacekeeper was the first U.S. ICBM to use cold launch technology. The missile was placed inside a canister and loaded into the launch facility.
When launched, high-pressure steam ejected the canister from the launch silo to an altitude of 150 to 300 feet, and once the missile has cleared the
silo, the first stage ignited and sent the missile on its course. This technique allowed SAC to launch the Peacekeeper from Minuteman silos despite
the fact that the Peacekeeper was three times larger than the Minuteman III.
Not dont forget the mobile midgetman they canned.
The Small Intercontinental Ballistic Missile (SICBM) or MGM-135A Midgetman was a development project from 1986 to 1992. The idea was to create a
lightweight, road-mobile ICBM that would be capable of surviving a Soviet nuclear attack. The U.S. military intended to base the SICBMs at widespread
locations, thus making them difficult to locate and destroy in a Soviet first strike.
The Scowcroft Commission had recommended the development of an SICBM in the early 1980s. President Reagan authorized full-scale development in
December 1986. On April 18, 1991, the system's first successful flight test was conducted. An SICBM was launched from a canister at Vandenberg Air
Force Base in California and reached its target at the Kwajalein Test Range in the Marshall Islands. President George H. W. Bush canceled the SICBM
program in January 1992, attributing reduced tensions between the U.S. and Russia following the end of the Cold War.
Nonetheless, the SICBM development program produced a prototype SICBM mobile launcher. Designed by Boeing Aerospace and Electronics and Loral Defense
Systems Division, it weighed 108,500 kg and was capable of traveling up to 88 km/h on highways. The launcher used a trailer-mounted plow to dig the
launcher into the earth for additional protection form a nuclear blast. Delivered to the U.S. Air Force in December 1988, the launcher was tested
until 1991 at Malmstrom Air Force Base in Montana.
