Strypi

Strypi is a family of US re-entry vehicle test boosters, anti-missile targets and sounding rockets.

[1] It is 31 inches (79 centimeters) in diameter, and has a maximum flight height of 124 miles (200 kilometers).

It was originally designed and built in 1962 by teams from the Sandia National Laboratories in an around-the-clock program that was a part of a larger nuclear weapons testing program, undertaken prior to the imposition of the Limited Test Ban Treaty (LTBT) in October, 1963.

Though it performed this function only once, in Test Checkmate of Operation Fishbowl, it became the "workhorse" of Sandia's rocket research program.

The Super Strypi was first launched on 3 November 2015, although on that test the first stage failed soon after lift-off.
