A rocket motor assembly (3) for use with an aircraft ejection seat comprises a rocket motor (4) having a rocket motor housing (5) and an exhaust outlet (6-9) to permit exhaust gas to be output from the rocket motor (4) along a thrust vector. The rocket motor assembly (3) comprises a first rotational coupling (12) which is configured to rotationally couple a first part (13) of the rocket motor housing (5) to a support structure (10) and a releasable coupling (14) which is configured to releasably couple a second part (15) of the rocket motor housing (5) to the support structure (10). The releasable coupling (14) is configured to release the second part (15) of the rocket motor housing (5) to permit the rocket motor housing (5) to rotate about the rotational coupling (12) to change the angle of the thrust vector of exhaust gas output from the exhaust outlet (6-9).
