[1][2] Ma is Professor and Director of the Institute of Power Electronic Technique Application at the Naval University of Engineering.
It is expected to be deployed on the Type 003, the PLA Navy's third aircraft carrier, which would make China the second country to develop the technology, after the US.
[3] In January 2019, Chinese media reported that Ma's team had developed electromagnetic railguns capable of firing projectiles at very high velocity, with longer range and higher accuracy than traditional artillery.
Military observers expect a modified version of the Type 055 destroyer to be equipped with the railgun, which would make China the first country to deploy the weapon on an actual warship.
[3][5] Ma is also credited for silencing noise of the PLA Navy's submarine's propulsion system thus making them less detectable on sonar.
