""Marshall Aerospace is proposing to fill key elements of the maritime patrol function by using existing C-130 assets, combined with equipment already developed by the Ministry of Defence," the company said.
Lockheed Martin EC-130J
The proposed "quick change conversion" would provide "an innovative and extremely cost-effective alternative for patrolling the UK's coastal areas", it added.
In addition to installing some of the mission equipment already acquired for the axed MRA4 fleet, such as the Thales Searchwater 2000 radar, the Cambridge-based company would make other adaptations.
These would include fitting an electro-optical/infrared sensor, onboard operator stations, sonar buoy dispensers and long-range fuel tanks. Some of the equipment "can be installed at short notice", said Marshall."http://www.flightglobal.com/articles/2011/06/21/358490/paris-marshall-aerospace-offers-c-130j-maritime-patrol.html
