Battleship (rocketry)

From Wikipedia, the free encyclopedia

In rocketry, a battleship is a non-functional rocket or rocket stage which is used to test configuration and integration of a launch vehicle.

The term should not be confused with the term boilerplate, which refers to a non-functional spacecraft.

A battleship version uses thick propellant tanks made of stainless steel or other corrosion-resistant metals rather than the light weight aluminum of the operational version. This is done mainly to test the liquid engines operationally and the configuration of the propellant tank passively.
