Very similar to the SA-128S MPG gravimetric drive system, this system provides decreased power usage it better work with the Spectre's smaller reactor. However its smaller diameter from the centre of mass allows a 20% increase in acceleration over the SA-128S fighter. Similar to the Phantom's systems, it incorporates an internal CBPU allowing an 80 km/s2 burst acceleration rate. It does, however, lack the large central CBPU of the Phantom and hence its 800 km/s2 acceleration abilities.
