Officials at Orbital ATK and ULA breathed sighs of relief on Thursday as the U.S. Senate voted overwhelmingly to exempt rocket engines from a sanctions bill targeting Iran and Russia.
The amendment to the sanctions measure exempted RD-180 engines used by ULA in the first stage of its Atlas V booster and the RD-181 engines Orbital ATK uses in the first stage of its Antares launch vehicle. Both engines are produced by NPO Energomash of Russia.
