Coyote Supersonic Sea Skimming Target

Overview

A Ramjet's fuel flow is metered by a hot gas valve prior to injection in the Ramjet Combustor.

The "Coyote" Supersonic Sea Skimming Target (SSST) is the only Ramjet Propulsion System in the U.S. currently operational and in production. Particularly, the SSST uses the VFDR Propulsion System.

Key Features

The next generation SSST VFDR systems use an advanced VFDR fuel. Both the current State-of-the-Art and Next-Generational Fuel models feature 7-inch dual inlets and can achieve Mach 3.25 at 30,000 feet.
