Everything you never knew you wanted to know about the Mercury Project
SOFAR bombs
From RixWiki
(Redirected from Sofar bombs)
SOFAR bombs were part of the range of recovery aids in the Mercury spacecraft. These were pressure triggered sonar bombs which would give a sonar fix if the spacecraft sank. Oddly enough they seemed to have failed to work in the one case where the capsule sank MR-4.
The SOFAR bombs were deleted after the MA-6 flight. This is mentioned in the description of spacecraft 18.
