I wondered if someone needed to demonstrate that they knew how to get a patent through the USPTO.

"Just come up with something weird, something that no one else would have thought of..."

 

[markfward]

...Or they decided drawings of a B-52 would be boring and old-fashioned. The patent has nothing specifically to do with the B-1B, and so they could have used drawings of any real or notional aircraft with a bomb bay.

I think it was clever marketing — if it were a B-52 in the figures, would the non-specialist press have picked it up and run with it? It's getting conversation started on social media with folks that don't generally follow things like patents on swinging a gun or laser out of an airplane, so I'd have to say Boeing's marketing folks succeeded.

Sure but do you really want to send the message, "we think our best ideas come from Wile E. Coyote cartoons"?

I'm honestly confused about why people think that this notion is so irrational. If you develop a palletized gun system that can deploy at substantial airspeed, slew around and accurately hit targets at some distance, then that same gun system can be mounted on other systems. Flip it upside down and put in on the back of a truck and nail ground and air targets. Put it on the deck of a cargo ship and surprise the hell out of those Somali pirates or Iranian gunboats or Chinese destroyers. Put one in a shipping container and plop it on top of your embassy or other fixed position.

Put the gun in a B-1 and get it on site quickly. Put it in a B-52 and loiter over the target. Put it in a B-2 and get there quietly. Hang a modified version out the back of a C-130 or C-17 and make an insta-gunship.

 

[sferrin]

If you develop a palletized gun system that can deploy at substantial airspeed, slew around and accurately hit targets at some distance

And there's the problem. If you've ever seen footage of Apaches firing their canon it's not all that accurate. If they're in a hover they can hit a single guy...eventually. Put that on a plane at 20,000 feet (to stay out of reach of small arms fire) and forget it.

You probably wouldn't send a B-1 or B-52 to nail a single guy. If you wanted to mess up a truck column, or theatrically turn a building or an industrial area or a missile launch site or a mass of infantry or a gunboat or a cargo ship or a train or low flying helicopters or cargo planes into confetti, this would be a dandy way to do it. Orbit at 20,000 feet and drop five thousand rounds of 40MM on a target, the *right* *kind* of target, and you'll leave an impression. With a 40MM cannon, the possibility certainly exists to use guided rounds. Imagine having a 40MM cannon capable of nailing one guy from five miles up... thousands of times. The mission limitation might be fatigue in the on-board WSO, so the plane might have to have remote gunners.

Still, consider: a B-1 with a high-precision gun is available, and you've just found out that the leader of ISIS is going to be standing on such-and-such a balcony hundreds of miles into enemy territory in a few hours. Soon enough that a B-1 could get there, but not an Apache, not a SEAL sniper team. It might be worth it to send that B-1. The guy is standing there chatting with his buds when BLAMMO his chest is turned into a cavity. Everyone starts looking around but can't see diddly because the gun is *miles* up and *miles* away. The B-1 gunner (now that he has definite confirmation that the target is indeed toast) gets to decide whether to call it a day and leave the rest of the people wondering, or start plinking. Individuals would be too busy simulating Brownian motion to be individually targeted (unless the rounds are laser guided), but their vehicles and structures certainly could be. If you want to be especially entertaining, use rounds that detonate a meter or two prior to impact, thus making a real mess of soft targets.

 

[taildragger]

So how is the above a better approach than using precision-guided cluster munitions? I think the USAF got it right when they put this in the "interesting but unnecessary file".

 

[Foo Fighter]

Perhaps the ability to reduce or remove the collateral damage from cluster munitions. Cluster munitions tend to kill just about everything in the vicinity of the target which is good for media coverage but not so good for the civilian population at ground zero or governments tainted by the act.

 

[TomS]

Such scenarios are more or less fantasy anyway, since actionable intelligence with that high precision in terms of both space and time is exceptionally rare. And the US has shown little concern about putting a PGM through roof of the suspect building on the occasions when such targets do present themselves. A B-1 with a bays full of SDBs or 500-pound JDAMs would be more than adequate for such missions.

This capability might be of some interest (though far from essential) in cases where bombers are used to provide close air support to troops on the ground. There are instances of B-1Bs (in Afghanistan mainly) making low-level, high-speed passes for suppression just from the sheer noise of their passage. Being able to deploy a gun to provide suppression with some actual lethality and standoff might be appealing. But it's a lot of bomb bay to tie up for such a capability.

The idea that a gun is somehow more of a precision weapon just isn't borne out by the reality on the ground. A gun fired at range from a high-speed aircraft is going to cover a wide area even when nominally shooting at a point target. That's just the nature of the beast -- dispersion is unvoidable. Even the guns on attack helicopters are far from precision implements, as Scott pointed out. Hence the interest in small guided weapons like APKWS to provide actual low-collateral-damage lethality.

See, this starts to sound like the Project Insight Helicarriers from Captain America: The Winter Soldier.

 

[Avimimus]

Yes, what I was thinking: A 40mm cannon firing guided rounds might be the exception (effective, relatively cheap, and usable outside of short range air-defenses).

 

[Orionblamblam]

See, this starts to sound like the Project Insight Helicarriers from Captain America: The Winter Soldier.

Science fiction has often been a decent way to envision future developments. A high altitude aircraft capable of sniping individual combatants at high volume, high rate and some distance would be a *fantastic* capability.

That was basically the concept in Real Genius but they used a laser in a weapons bay in a B-1. Why not do the same instead of a projectile weapon? Make a self-contained pallet that slides into one of the bays on a B-1B.

 

[Orionblamblam]

Not really. Sure, knowledge about "hey, you know that *one* guy we really want?" might be rare, but "hey, there's a whole camp of jackholes we'd like to kill" is fairly common. The capability being discussed here *might* (and, eventually, *will*) allow an aircraft to take out individuals. If you have a series of remote gunners or a really good AI hooked up to sizable optics and laser guided ammo, you could shoot every male of military age in a camp, or everyone holding an AK-47 or an RPG, or everyone *not* wearing an orange jumpsuit.

The ability to turn an entire camp into a smoking hole is a fine demonstration of power. The ability to turn *specific* people in a camp into individual smoking holes is a whole new level of power projection.

A B-1 with a bays full of SDBs or 500-pound JDAMs would be more than adequate for such missions.

Sure, if your goal is widespread and rather uninspired destruction. and that's fine for many applications. But there's times when you want to do something different, or otherwise we'd simply drop bobs on *all* problems.

dispersion is unvoidable. Even the guns on attack helicopters are far from precision implements, as Scott pointed out. Hence the interest in small guided weapons like APKWS to provide actual low-collateral-damage lethality.

And since there are guided .50 BMG rounds, a 20MM and especially a 40MM with guided rounds is pretty straightforward. Imagine how many tens of thousands of rounds of guided 20MM a B-52 could carry, along with the optics needed to pick out individual targets. With a proper controlling AI software system, that B-52 could overfly enemy territory and apply one 20MM round to each person. A single B-52 could wipe out an entire invasion force landing in, say, Taiwan or Ukraine (by targeting everyone wearing a particular nations uniform... killing them, but leaving a lot of their *stuff* intact, and *not* trashing the friendly territory the B-52 is protecting). It could kill the crews of every single small attack boat within 20 miles. It could turn an infantry assault sweeping west through Poland into just a whole lot of dead guys. And missiles and aircraft sent to bring that B-52 down had better attack from above, because they won't get close.

There was an article in an old MILTECH back in the late 80s/early 90s where they'd developed a guided 40mm round. It used single-shot side thrusters like the ASM-135 KKV. They said they could scale it down to 20mm or up to 16" rounds. As Exacto demonstrated, the options are greater now.

What stuff is being made up? Guns? We have them. Laser guided ammo? Have it. AI systems that can distinguish types of targets? Have it (quite possibly your *phone* has it). Airborne optics? Got it.

DoD FY2018 Rapid Innovation Fund

U.S. Special Operations Command (USSOCOM)
Requirement #: SOCOM-18-BAA-RIF-0001
Title: Guided 30MM Ammunition Capability
Military System or Acquisition Customer: Program Executive Office (PEO) – Fixed Wing
(FW)
Description: Provide an enhanced accuracy, guided 30MM ammunition capability that is
compatible with current AC-130 W/J platforms’ Mk 44 Bushmaster II (GAU-23) automatic
cannon weapon systems. Deliver a 30MM round capable of receiving and responding to
externally provided post launch course corrections to accurately engage designated moving and
stationary ground targets, with guidance systems that are compatible with current Precision
Strike Package (PSP) on the AC-130 W/J aircraft configurations with little or no hardware
modifications. Proposed software modifications should lead to demonstrable capability by minor
additions to PSP software in about six months with full capability fitting in the annual PSP
software release cycle. The guided 30MM round target circular error probability (CEP) must be
predictable and provide considerable improved accuracy over standard unguided 30MM
ammunition. The guided 30MM round must operate within the operating envelope of the
AFSOC AC-130 W/J, altitudes (15,000 – 25,000’ MSL), ranges (1.0 - 10.0nm) and slant ranges
(2.5 – 3.0nm). Use of high fidelity modeling throughout development is encouraged to
determine the optimal munition configurations, characteristics and maximize the value of range,
ground, and flight testing. The initiative will conclude with a guided 30MM ammunition round
design, guidance and control system, and tracking system that has been demonstrated in a nearfinal
and realistic configuration.

Bad to the Bone: Here's the scoop on Boeing's plans to turn the B-1B into a supersonic gun ship | Fighter Sweep

On May 8th of this year, Boeing was granted a patent that shows a number of potential cannon configurations for legendary supersonic bomber, the B-1B

The USN could use a F-111 replacement for the deck. Retiring that maintainence heavy craft ;} is just a mistake. Bones could help w/ the Pacific range problem
. Current and near future Carrier based craft carry is conspicuiously low.
A long range, near recoiless. gun suspended from a Bone could surpress IADs from distance.

Expanded Carriage Demonstration Showcases Possible B-1B Capability

"EDWARDS AFB, Calif. --- The 412th Test Wing, along with Air Force Global Strike Command and industry partners, held an expanded carriage demonstration with the B-1B Lancer bomber at Edwards Air Force Base, California, Aug. 28.

The demonstration showcased the feasibility of increasing the B-1B weapons capacity to integrate future advanced weapons.

The two potential programs – external carriage and long bay options – would allow the B-1B to carry weapons externally, significantly increasing its magazine capacity for munitions, as well as adding larger, heavier munitions, such as hypersonic weapons.

“The purpose of the demonstration was to show that we’re still able to move the bulkhead from the forward intermediate bay to the forward location; increasing the intermediate bay capacity from 180 inches to 269 inches, said Lt. Col. Dominic Ross, B-1B program element monitor, AFGSC. “Additionally, we demonstrated that we can still carry weapons externally on six of the eight hard points, which increases our overall carriage capacity.”

Ross said the expanded capabilities will be conventional only, keeping the aircraft compliant with New Strategic Arms Reduction Treaty, or New START. "

Which makes you wonder why they ever got rid of the capability.

edit: 269" gives them enough room for a GBU-57 MOP.

 

[Mark S.]

Don't think they got rid of the capability but rather never used it. The long bay option was for the ALCM and ACM. The ALCM could only be carried internally because of the harsh acoustical environment that it wasn't designed for under the aircraft and the ACM integration was canceled at the end of the Cold War. At that time there was no need for carrying long weapons. Interesting that the AGM-183A fits in the long bay. Is the B-52's bay 269 inches or was it designed to fit in the B-1's bay? Just read where the bay was designed so that the bulkhead could be removed entirely resulting in a 31 ft. bay. Think the rotary launcher for that length would have too great of diameter to be useful (rule of thumb suggests 15 inches) but sure they could come up with other suspension systems.
