Polaris Surface Surprise

Posted on by One comment

Some 60 years ago this month, an important show of force for the Fleet Ballistic Missile Progam:

The Lafayette class ballistic missile submarine USS Henry Clay (SSBN-625) launches a Polaris A-2 missile from the surface of the Atlantic Ocean off Cape Kennedy, Florida, on 20 April 1964. This was the first demonstration that Polaris subs could launch missiles from the surface as well as from beneath the surface. Just 30 minutes earlier, Clay had successfully launched an A-2 missile submerged.

The above tactic would come in handy if, say, the FBM was stuck in port and an emergency launch order came, or, for instance, if surfaced in the icepack.

The objects flying through the air around the missile are launch adapters designed to detach themselves automatically once the missile has left the tube. The sub’s slight port list is a standard part of surface launch procedures. The tall mast is a temporary telemetry antenna installed for operations at the Cape only.

The 15th of the famed “41 for Freedom” boomers, Henry Clay was launched on 30 November 1962 and commissioned on 20 February 1964.

Henry Clay was decommissioned on 5 November 1990 and her recycling was completed on 30 September 1997.

Pitching Clay, or, the ’41 for Freedom’ can fight surfaced, too

USS Henry Clay (SSBN-625) launches a Polaris A-2 SLBM from the surface of the Atlantic Ocean off Cape Kennedy (Canaveral), Florida on 20 April 1964. The objects flying through the air around the missile are launch adapters designed to detach themselves automatically once the missile has left the tube.

The goal of the Polaris program was to launch a ready missile by 1965, and Clay was one of the last pegs to make it a reality.

Named in honor of founding father Henry Clay, perhaps best known as the “Great Compromiser,” the boomer was part of the Lafayette-class of ballistic missile submarines that were made in the “41 for Freedom” program in the 1960s, all subs named after famous Americans to include the honorary Yank, the Marquis de Lafayette. Clay was commissioned 20 February 1964 and was decommissioned 5 November 1990 for recycling.

Seldom heard from, the boats of the 41 For Freedom program made an incredible 2824 strategic deterrent patrols during their time on earth, each typically about 65 days. This is about 502 patrol years at sea during the Cold War.
