It is also possible that the emerging arsenal plane could be a modified C-130 or combined version of a B-52 and C-130 drawing from elements of each, Pentagon officials said.
Using a B-52, which is already being modernized with new radios and an expanded internal weapons bay, would provide an existing “militarized” platform already engineered with electronic warfare ability and countermeasures designed to thwart enemy air defenses.
Defense Secretary Ashton Carter said “Arsenal Plane” development would be funded through a $71 billion research and development 2017 budget request.
An "Arsenal Plane" networked to F-22 and F-35 stealth fighters would enable the fighter aircraft to maintain their stealth properties while still having substantial offensive bombing capability. If stealth fighters attach weapons to their external pylons, they change their radar signature and therefore become more vulnerable to enemy air defenses. If networked to a large "flying bomb truck," they could use stealth capability to defeat enemy air defenses and still have an ability to drop large amounts of bombs on targets.
Such a scenario could also likely rely upon now-in-development manned-unmanned teaming wherein emerging algorithms and computer technology enable fighter jets to control the sensor payload and weapons capability of nearby drones from the cockpit of the aircraft. This would enable Intelligence, Surveillance and Reconnaissance assets to more quickly relay strategic or targeting information between fighter jets, drones and “Arsenal Planes.”
A B52 could modified to carry 80 to 200 air to air missiles or drones. This would be about 20 to 50 times more than the F22 or F35. The F-22 can fit four air-to-air missiles and two 1,000-pound bombs in its internal bay, whereas the F-35, next to two air-to-air missiles, can only carry two 2,000-pound bombs in its stealthiest configuration.
Engineers are now equipping all 76 of the Air Force B-52s with digital data-links, moving-map displays, next-generation avionics, new radios and an ability to both carry more weapons internally and integrate new, high-tech weapons as they emerge, service officials said.
The new B-52 “Arsenal Plane” could, for the first time, configure a primarily air-to-ground bomber as a platform able to fire air-to-air weapons as well – such as the Advanced Medium Range Air to Air Missile, or AMRAAM.
The B52s are already being modified with the 1760 Internal Weapons Bay Upgrade, or IWBU. This will allow them to internally carry up to eight of the newest “J-Series” bombs in addition to carrying six on pylons under each wing.
The first increment of IWBU, slated to be finished by 2017, will integrate an internal weapons bay ability to fire a laser-guided JDAM. A second increment, to finish by 2022, will integrate more modern or cutting-edge weapons such as the Joint Air-to-Surface Standoff Missile, or JASSM, JASSM Extended Range (ER) and a technology called Miniature Air Launched Decoy, or MALD. A MALD-J “jammer” variant, which will also be integrated into the B-52, can be used to jam enemy radar technologies as well.
