Jack Zerr, the Multi-mission Maritime Aircraft (MMA) programme manager described the aircraft as “A bit of JSTARS (Joint Surveillance Acquisition Radar System), a little bit of AWACS and a little bit of MC2A (Multirole Command and Control), but with the added ability to go and kill a submarine.”
The MMA, US Navy designation “P-8A Poseidon” and Indian Navy designation “P-8I”, is based on the 737-800 fuselage and the stronger 737-900 wing, with raked wingtips that have anti-icing along all leading edge slats. A weapons bay aft of the wing, (effectively in the aft hold) carries internal stores such as Mark 54 torpedoes. There are four underwing hardpoints for AGM-84D Harpoon or similar. The fuselage is strengthened for weapons employment and to permit ASW profiles. Up to seven mission consoles and a rotary sonobouy launcher can be fitted in the cabin. Like the AEW&C, the MMA will have 180kVA IDGs as standard. The MMA also has an in-flight refuelling receptacle over the flight deck.
Northrop-Grumman provide the electro-optical/infrared sensor, the directional infrared countermeasures system and the electronic support measures system. Raytheon provide an upgraded APS-137 maritime surveillance radar system and signals intelligence (SIGINT) solutions. Finally, Smiths Aerospace provide the flight management system and the stores management system. The flight management system provides an open architecture along with a growth path for upgrades. The stores management system permits the accommodation of current and future weaponry. The basic open architecture of the MMA is believed to have 1.9 million lines of code!
Much of the provisioning for the modifications is being done by Boeing during production to save time and cost at the conversion stage. Boeing has built a third production line which is dedicated to the MMA alongside the commercial 737 assembly. After the aircraft are assembled at Renton they are flown over to Boeing Field for mission system installation.
