What unit is this Grim Reaper Flight patch?

[vintageproductions]

This came out of a Vietnam 433rd TFS group.

 

It's about six inches tall and Japanese machine embroidered.

 

Ran it through USAFpatches.com but nothing came up.

 

 

 

Thanks

VF 101 US Navy are the Grim Reapers..

The AF also uses the Grim Reapers on some of their stealth aircraft.

Like the 4451st Test Squadron

493rd TFS are the grim reapers. Maybe an AC-130 unit?

Cool patch.

It could be a class patch for USAF UPT since it uses the term Flight. Might have been like G Flight for a certain year class.
