Having already covered one tier of long range bombers—the converted airliner, what next?
Diversity in long range platforms.
Build a new long range bomber based on the B-1b concept.
-Swing wing, 4 engines
-Avionics from the F-35 and Super Hornet—just about the whole package, including a E/O built into the nose like the F-35.
“Balanced survivability.” Not stealth but more of a tuned low observable airframe with a defensives system similar to a Super Hornet Block II. This approach would mean low level penetration when needed. This means the 4 motors should be lower-altitude grouping friendly (fuel burn) like the F135 motor for the F-35.
Four crew and ample space for a relief crew. Pilot, Co-pilot, Offensive Systems Operator. Defensive Systems Operator.
Range? Probably about that of the current B-1. Not a great range star but not bad.
Most of the cost in today’s B-1 revolves around an older technology fight control setup, older engine setup, older cockpit setup and so on. This makes the upkeep expensive. A new build, B-1 style of aircraft would be cheaper to operate on all fronts.
Not a next-war-itis jet either. When today’s B-1 shows up for CAS, it can stick around for a while and bomb until the controller on the ground is happy.
Nuke mission? No. This adds more expense. If the “triad” goes away someday, we won’t miss it.
The third tier of long range bombing? That would be the UCAS-N in USAF colors. 50 hours of flight time with refueling, broadband stealth, and when fence-in, uses the same method of targeting and control as a Tomahawk IV. This is: different degrees of network control based on the threat and the presence of network denial. After all, certain targets that are strategic in nature are fixed. Of course if the network is permissive, then the targeting is more versatile. UCAS-N reduces the risk to the Navy by having the USAF get in and use it for conventional airfield ops only.
So then, a possible idea for long range bombing. Diverse. Complementary.
-Converted conventional airliners
-A modernized B-1 concept
-UCAS-N
This could be done and put into effect. It is also much more achievable than the failed 2018 “Great Pumpkin” bomber.
