Hi,

the American Rocket (Amroc) and Space Services (SSI),which had originally
planned to operate low-cost commercial launch vehicle services in 1988.

Amroc proposed a four stage vehicle propelled by hybrid motors which use a solid fuel and liquid oxygen. In total there were to be 19 motors, 12 of which were clustered around the central tank as the first stage, 4 formed the second stage, 2 the third stage and the final motor the fourth stage. The vehicle was to be 25 m long and be capable of placing a payload of 1360 kg into a polar orbit. The first flight was envisaged for 1988 but the vehicle did not eventuate and Amroc instead concentrated on the manufacturing of rocket components.
SpaceDev Corporation of San Diego acquired exclusive rights to the intellectual property of the former American Rocket Company (Amroc), in particular the designs of the hybrid rocket motor technology. Hybrid rockets combine a liquid fuel oxidizer and solid fuels (hence hybrid) making for an environmentally cleaner motor which is non-explosive and less expensive to manufacture. No plans have been made for the development of a launcher which will utilise the technology.

The Amroc Aquila proposal envisaged a family of three launch vehicles. The Aquila-1 vehicle would be able to place 315 kg into low Earth orbit, a version designated Aquila-21 would have had a capability of 1135 kg, whilst there are also references to an Aquila-421.

Here is some further information about the Amroc Aquila.

After the failure of the SET test vehicle with the H-1500 hybrid engine on 5 October 1989 from Vandenberg due to insufficient thrust for lift, no further flights in the ILV programme were undertaken and instead Amroc used the clusting concept with the H-1800 rocket engine to propose the Aquila family of launch vehicles.

Name Stage 1 Stage 2 Stage 3 Stage 4
HyFlyer 1 x H-1800
Aquila 1 1 x H-1800 Orbus 21 U-75 or Orbus-7
Aquila 21 2 x H-1800 1 x H-1800 Orbus 21 U-75 or Orbus-7
Aquila 31 3 x H-1800 1 x H-1800 Orbus 21 U-75 or Orbus-7
Aquila 421 4 x H-1800 3 x H-1800 1 x H-1800 Orbus 21

HyFlyer was to be a sub-orbital test vehicle that was to perform its first flght in 1996.

Apart from the Aquila 1, the Aquila family of launch vehicles was to consist of a first stage of two or more strap-ons attached to the second or core stage. These two stages were topped by a further two stages creating a launch vehicle with a heigth of 19.50 m. The Aquila 21 version was expected to place 1360 kg into a low-Earth oorbit.

None of the Aquila launchers ever flew as the company went bankrupt in the summer of 1995.

In August 1998 SpaceDev Corporation of San Diego acquired exclusive rights to the intellectual property of the former Amroc, in particular the designs of the hybrid rocket motor technology.

I wonder of anybody has a picture or drawing of the Aquila and cares to post it here.
