Mustard


The British Aircraft Corporation "Multi-Unit Space Transport And Recovery Device" design of 1964-1965 was a winged two-stage-to-orbit reuseable space shuttle using the 'triamese' concept. The three components of the design were lifting bodies with a configuration similar to the American HL-10 vehicle. BAC sought to reduce development cost by use of two boosters nearly identical to the orbiter vehicle.

Although the orbiter's engines would be firing at lift-off, it would start its burn to orbit with nearly a full fuel load. Propellant from the two boosters would be pumped into the orbiter prior to separation. This would potentially have allowed the orbiter to reach the moon - a unique capability for a winged reusable design. Various configurations were examined (back-to-back, triangular back-to-back, 2 x back-to back and 1 inline). Developed by a team led by Tom Smith, the MUSTARD vehicles would have been capable of being flown back via remote control or by a pilot.

Flyaway Unit Cost $: 54.000 million in 1985 dollars.
