All about MQ-4C Triton

The  MQ-4C Triton is worth over Rs $200 million, positioned for the US Central Command area over the Gulf region.

Unlike traditional aircraft, the Triton provides long-hour strategic surveillance over chokepoints. It is engineered for persistent, large-scale maritime surveillance, frequently serving as the high-altitude eyes for P-8A Poseidon patrol planes. Triton is the only autonomous high altitude, long endurance (HALE) maritime aircraft capable of operating at altitudes above 50,000 ft, for 24-plus hours with a range of 7,400 nautical miles.
