ABSTRACT:
A bottom release mechanism for a sonobuoy is provided in which a removable end cap is provided with a deformable detent member in the form of either a leaf spring or frangible member, which normally maintains a spring-loaded pin in locking engagement with the sonobuoy package thereby to lock the end cap in position at the bottom of the sonobuoy package. Upon water impact the deformable detent is deformed out of engagement with the spring loaded pin thereby releasing it which permits release of the end cap from the sonobuoy package. The use of the deformable detent member increases reliability of end cap release over large entrance angles of the dropped sonobuoy with respect to the surface of the ocean.
