test segment was lost due to improper fuel casting. In 1990, prior to the first stacking of the motor, the crane assembling the booster dropped a segment, causing it to roll away from the test area and explode. One worker was killed and nine injured. The mishap also caused the first launch of a Titan IV with SRMU boosters to be delayed; originally, the new booster was expected to launch in 1991. One year later, in the SRMU's first test firing, the motor exploded upon ignition. The motor had to be thoroughly redesigned. In the meantime, Martin
Marietta placed an order for more UA120 motors, as the SRMU would not be ready in time. At the same time, Hercules' costs severely exceeded the value of the contract it had been awarded. The
317:. An electrical detonator is used to activate pyrotechnics for booster ignition and staging, and for the flight termination system, which consists of a shaped charge explosive designed to destroy the booster in flight. The booster is attached to the vehicle core by a reinforced aft skirt near the base of the motor, which also transmits the thrust loads between the two structures. This skirt also contains the assembly for the thrust vectoring control (TVC) system. The nozzle itself is made of steel, wrapped in an epoxy composite similar to that on the motor segments. Additional structural elements include steel bands at segment joins. Each segment is manufactured separately, then integrated at the launch site.

By 1994, it had become apparent that Martin
Marietta's additional order for UA1207 boosters, combined with a decline in demand for launches, was resulting in a surplus of completed Titan IV carrier rockets. As a result, the SRMU would not be needed until 1997. A total of 17 flight sets of boosters

Numerous delays took place during development. Martin
Marietta changed the majority of its design requirements for the SRMU between 1988 and 1990, rendering progress slow. The SRMU was the largest motor Hercules had ever built, and it was also its first use of HTPB binder. Early in development, a
