The Mobile Proton Torpedo Launcher-2a—also called the MPTL-2a—was a medium mobile proton torpedo launcher crawler artillery platform that could fire proton warheads from a nine-tubed launch assembly deployed from its armored shell. Used by the Rebel Alliance, the MPTL-2a was developed to counter serious design flaws being exploited by the Galactic Empire in its predecessor, the MPTL-L.
This track-treaded mobile weapons platform was designed and produced by Loratus Manufacturing. When ready to deploy proton torpedoes, the armored shell of the vehicle would split open to expose nine launch tubes. When used in coordination with spotter droids that sensor pinged heavily armored enemy units, the MPTL-2a had a maximum firing range of more than 20 kilometers. However, range and accuracy could be severely hampered without assistance from sensor droids or spotting units.
Due to the slow responsiveness and turn rate of the MPTL-L, Imperial artillery units began exploiting its sluggishness during the Galactic Civil War. The Rebel Alliance sent Loratus Manufacturing desperate requests for design upgrades, and the resulting 2a variant was lighter, making it more maneuverable and faster in deploying its launch assembly than the MPTL-L. However, the lightweight build hampered the launcher's stability and range, and the initial upgrades performed poorly during field tests, requiring the addition of gription stabilizers to steady the vehicle so the launch assembly could effectively fire. Although its increased mobility over the MPTL-L made it less of an easy target, it was not a direct combat vehicle. Therefore, Rebel Commanders attached armed escorts to the vehicles or kept them out of range of heavy fire. In spite of its few shortcomings, the MPTL-2a was a significant upgrade over the MPTL-L design due to its lightweight build and—with the accompaniment of spotter units—its extended weapons range.
