WASHINGTON — The Minotaur II+ rocket, which the US will use for the LGM-35 Sentinel intercontinental ballistic missile [ICBM] and the W87-1 nuclear warhead – the Mk21A, made its first test, but was unsuccessful. Days ago, on July 7, during the first test at the Vandenberg Space Force Base [VSFB]the rocket exploded 11 seconds after launch.

Immediately after the explosion, which occurred very close to the launch pad, debris fell into the area. VSFB officials reported no injuries, but said the blast caused a fire at the North Base. A press release from Col. Kris Barcomb, deputy commander of the Delta 30 space launch, confirms what we know, adding that the base’s priority has always been safety, and after the incident, emergency crews responded immediately. At the moment, the cause of the explosion is not clear, but the base announced that an investigation had been launched.

The new US nuclear program includes the phased retirement of 400 Minuteman III intercontinental ballistic missiles and their replacement with the LGM-35 Sentinel based on the Minotaur II+e rocket. The launch was scheduled to be the first test supporting the development of the Air Force’s new Mk21A re-entry vehicle.

According to Pentagon plans, new ICBMs should begin entering the US strategic nuclear forces’ roster in 2029 to replace the outdated Minuteman III missiles that have been in service since the early 1970s.

The missile is being developed by Northrop Grumman Corporation under a $13.3 billion US Air Force contract. The United States Department of Defense estimates that the cost of acquiring new missiles will be more than $95 billion.

The United States now has 400 Minuteman III intercontinental ballistic missiles, each of which can deliver up to three nuclear warheads to a range of 12,000 km. They are the only intermediate force-based ballistic missiles in the triad of US strategic nuclear forces.

Minotaur II+ is a suborbital launch system. At the moment, the US Air Force is at stage 3 of its development – launch and flight tests. By July 7, the Minotaur II+ had made several test launches, with the latest being the only failed launch.

The Mk21A is the new carrier of the W87-1 nuclear warheads. This model of nuclear warhead is extremely powerful. According to data available from open sources, its power is equal to 300 kilotons, 15 times more powerful and devastating than the “Fat Man” bomb dropped on Nagasaki in 1945. The W87-1 is part of the W87 family, a warhead with a long history and one of the oldest in the US Army inventory. Sources say the W87-1 has improved safety in its use.
