American sea-launched orbital launch vehicle. SEALAR (SEA LAunched Rocket) was yet another attempt by Truax Engineering to get the amphibious-launch concept off the ground. The project received some Navy Research Laboratory funding in the early 1990's, with a planned first launch date of 1996. A production model would have been able to achieve orbit at an estimated cost of $ 10 million per launch. As with the earlier Truax projects, it did not achieve flight test status.
