OpenHarrier

Building a replica of the Stencil SJU-4/A ejection seat for the AV-8B Harrier.

The AV-8B Harrier can be fitted with 2 different ejection seats. While the Martin Baker MK10 was used in most British AV-8B Harriers, the USMC (United States Marine Corps) Harriers mostly used the SJU-4/A ejection seats. I say mostly, because there are/were some AV-8B’s in the USMC that had MK10 seats. I am uncertain if that was because some of the Harriers were acquired from the Royal Navy and Royal Airforce after the United Kingdom’s Harriers were retired and some of them may have been transferred to the USMC.
