The Chaffee-type shuttlepod had a small cockpit with room for about four people. The primary power grid was powered by the impulse engines. The grid made no use of antimatter. For this reason it was capable of entering areas of subspace metreon radiation that would normally collapse the dilithium matrix of a warp core. The pod also had back-up power in case the impulse power failed. There were also primary and secondary navigational computers. The pod was protected with deflector shields.
