 The United States Coast Guard had a short-lived NFO community in the 1980s and 1990s when it temporarily operated E-2C Hawkeye aircraft on loan from the Navy.Following a fatal mishap with one of these aircraft at the former Naval Station Roosevelt Roads, Puerto Rico, the Coast Guard returned the remaining E-2Cs to the Navy and disestablished its NFO program.Training for student NFOs (SNFOs) starts out the same as for student naval aviators (SNAs), with the same academic requirements and nearly identical physical requirements.
