Abstract
Abstract A flechette weapon system which includes a missile operated mechanism for ejecting a plurality of flechettes from a missile. The mechanism includes a valve designed to automatically open at a predetermined pressure in the missile''s motor pressure time operation. As the valve opens missile motor pressure passes through the valve and pressurizes an ejection piston and ejects the flechettes supported on the piston.
