The Strike Raptor is a proposed platform to replace aging strike aircraft like the F-15E and retired aircraft that were never replaced like the F-111 and F-117. If built, it would be comparable if not superior to the F/A-22 in performance, while being able to carry a significantly heavier payload for medium range bombing missions. Lockheed Martin has suggested that the F/B-22 could attack in a large formation that is escorted by F/A-22s but can also fly solo and defend against any attacking aircraft. The Strike Raptor could enter the 2018 bomber competition that will satisfy the Air Force’s need for a supersonic bomber able to support multiple battles that are widely dispersed. A bomber variant of the Raptor would be particularly attractive to the Air Force because of its ease and inexpensiveness of development because it is heavily based on the existing Raptor. Some designs even call for the use of existing Raptor fuselages to be affixed to larger wings. The F/B-22 could one day fly with the 2037 bomber that will be unprecedentedly fast and heavy and able to strike huge areas.
Below is a discussion between Lockheed Martin officials and high-ranking military officers on the abilities of the Strike Raptor:
If Lockheed Martin makes the decision to go ahead with the F/B-22 project, it would probably be entered in the 2018 medium-sized bomber competition. However, this would be no guarantee that the Strike Raptor would be chosen to enter service. Certainly the Bomb Raptor would be a heavy contender in the contest, but several other competitors are already in development. Already about a dozen concepts for the competition have been released from many of the major aerospace manufacturers including Boeing, Northrop, and McDonnell Douglas. The new Raptor would have to prove itself against designs like a modified B-2 (seen above), a bomber variant of the YF-23, and perhaps the most notorious B-1R from Boeing. Given that manufacturing of the F/A-22 has been slow and over budget, Lockheed might have an uphill climb with convincing the military they can deliver. Even with that said, the F/B-22 design appears to be the best suited for the role required of the 2018 bomber and would probably be the early favorite if entered into the contest.

The possible designs for a Strike Raptor seem to be endless. The majority of the designs possibilities are heavily based off the F/A-22. Most designs show a lengthened or stretch version of the original F-22, but there are a number of other possibilities that would be more economically appealing and others that would give better performance. A possible combination order of multiple designs might be able to fill several holes in the Air Force, and for a relatively low price. The most economical and easily-implemented design to come out of Lockheed is a simple upgraded wing. This new wing would be about twice as long and wide as the standard Raptor wing, and would have more depth to accommodate weapons. If purchased, such a wing would be easily fixed to existing F-22A Raptors, and would save the Air Force billions because they would not have to order new aircraft. The new wing would be able to hold approx. a half dozen small diameter bombs and add additional fuel tanks to increase the Raptor’s range to strike further inland and fly multiple missions in a single flight. Another possible design being explored is an F-22B. It would be a new 
model F/A-22 that would continue to be mainly a fighter aircraft, but would have more weapons stations and as it would be larger and heavier, would probably have a role similar to the F-15E now. The F-22A, whose ground attack capabilities have been questioned, would be able to focus on air dominance while the F-22B (which could have two seats) would fill the strike fighter need. The most common design for the F/B-22 is a Raptor-resembling model that is twice the length as the original and has delta wings. Such an aircraft would be able to carry upwards of 35 SDB’s and would have a range equal to that of legacy regional bombers like the F-111 and F-117. This plane would be able to fly faster that the F/A-22, but would give up supercruise and thrust-vectoring. It would lack tail pieces, thus making it stealthier. The most radical and expensive possibility would be a bomber based on the X-44 Manta project, also derived from the F-22. This design (shown above) would also lack a tail and would be very stealthy. But, its wings are so huge that it gives the aircraft the appearance of a sideways diamond. Without a tail to aid in stabilization, such a design would be very hard to control and would require funding for new tech development that simply would not be allocated by the military. However, if the design could be figured out, this aircraft would be every bit as fast and stealthy as the F/A-22, but would be able to carry more than 50 SDB’s and could have double the the range due to the lift of the massive wings.
