In most designs, the seat is propelled out of the aircraft by an explosive charge or rocket motor, carrying the pilot with
Martin-Baker Mk.8 is the designation given to two distinct British ejection seat types designed and built by Martin-Baker.The original use applies to a seat developed for the cancelled BAC TSR-2 strike aircraft project of the 1960s, re-use of the designation applies to a lightweight version of the Martin-Baker Mk.10 seat for the Short Tucano and other similar military training aircraft.
The Mk.6 seat was developed from the earlier Mk.4 design by the addition of a rocket pack to enable zero-zero capability. [1] A variant of the Mk.6 was fitted with a compressed air cylinder crew breathing system to provide underwater ejection capability for the carrier-borne Blackburn Buccaneer aircraft.
The Mk.4 seat was designed as an improved, lightweight version of earlier Martin-Baker seats for installation in a range of lighter, smaller aircraft types. [2] Improvements included a single combined seat and parachute quick release fastener (QRF) and a snubber mechanism to allow crews to lean forward without loosening the harness. [ 2 ]
The Mk.5 seat was developed alongside the Mk.4 design to meet the needs of the United States Navy. Compared to the Mk.4 seat the structure and harnesses were strengthened to withstand higher crash landing loads, this resulted in a slight increase in weight. [2] Canopy breaking horns were added to allow ejection through an unjettisoned canopy. [2]
The Mk.7 seat was developed from the earlier Mk.5 design by the addition of a rocket pack to enable zero-zero capability. [1] A large upgrade program to retrofit Mk.7 seats to all Lockheed F-104 Starfighter aircraft in German Air Force service was initiated by Johannes Steinhoff in late 1967, this measure improved the type's safety record and several other European nations operating the ...

For ease of maintenance the Mk.10 was designed with modular assemblies, avoiding the need to remove the whole seat from the aircraft for minor servicing tasks. [1] The first successful emergency use of a Mk.10 seat involved a Red Arrows BAE Hawk on 17 May 1980 after the aircraft struck the mast of a yacht moored offshore at Brighton. [2]
