We're at the stage now arguably, where we simply can't afford any more high-stake recapitalization gambles and should instead focus priority on reliability and prudence.

Thus, perhaps the currently envisioned LRS-B requirement could be broken up into into something like: 1) re-engining around 50x B-52 with more efficient commercial liner engines (4x engines replacing the 8x polluting and inefficient TF33) , along with other avionic/EW/SOJ upgrades + 2) 50x or so B-1B retrofitted to a B-1R type concept (w/ reliable GE-132 engine replacement, not the more expensive and less efficient F119), along with avionic and weapon system upgrades + 3) a slightly larger UCAV model, capable of employing JASSM-ER class ordnance?

The costs would likely be considerably less overall, while reliability and delivery to force structure completed much sooner.

Some of the savings could be re-invested in actual, required next-gen stand-off munition classes likely not being affordable if otherwise sinking extreme sums of investment into a next gen Bomber which may or may not come out the other end, later than required?



GEO I think that you may have answered your own question here.

Both the upgraded B-1BR and the upgraded B-52H won't transform into hugely better aircraft with those costly changes. They may do what they do right now somewhat more efficiently but their basic capabilities won't be transformed. The B-52 won't become supersonic or stealthy, it will still be ugly and do it's job. The B-1B may be able to cruise supersonic longer than the current sprint capability but it still won't be able to do that for very long so it will largely be the same aircraft it is now. If you talk to B-1 maintenance crews, it isn't the engines that have them working overtime to maintain ready rates, it is old ECM systems and mazes of 80s era wiring, swing wing glove stuff etc. Both these cold war machines are still going to need large wing staff to support them.

But the improved stand-off weapons development has a lot of pluses.
You don't need to make ANY significant improvements to these two aircraft to accept those new weapons. And those new weapons can be used on the NGB if it ever appears. I don't see a huge downside to pushing forward on the new stand-off weapons and kicking the bomber upgrade 'can' down the road.

Yes, we're (they're) able to shoot down non-maneuvering bright-white and gold plated satelites w/o countermeasures. Seems I recall a number years ago that some rat leaked out LO satelite tech... Probably a Democrat sympathizer, or foreign national.



Troll much?

B-1B is an awesome plane. I'd give my left **t for an upfront office. B-1R if if were stealthy, would make an awesome force multiplier if you stuff 24 120s (total) into the 3 weapons bays. B-1R just isn't survivable enough for a modern enemy on a deep strike. No IR suppression, no airframe LO. Always been my favorite plane on beauty alone.... Unless the Northrop YF-23 bomber sibling were to ever come to fruition.

Yeah, vermin get to experience glorious deaths like spring traps and buckshot while rolling around in the excrement they came from.

Right, because adding in a non-sequitur about democrats and treason is the epitome of maturity and staying on topic.

FWIW Aviation Week is reporting in their Dec. 3, 2012 issue that L-M is working on the LRS at the present time and that N-G is building a complementary unmanned Recce aircraft.

One or what two extra stops at the tanker on a round the world flights not bad.

I got a $20 on the next bomber running two F135 based engines. Devil

You might lose - probably going to be whatever makes it out of the AATE program, which might be a derivative of the F135 - or something GE comes up with...

Isn't AATE an Army program? You know... for helicopters?

[edit] Perhaps you meant AETD, which replaced ADVENT after P&W was substituted for RR. http://www.aviationweek.com/Article.asp ... ml&p=1

Yea, you're right. There was an older USAF program called (V)AATE which was what I remembered off the top of my head - and forgot the V for Versatile. I think it spawned ADVENT, and then I guess ADVENT was resurrected as AETD.

That's the one. I hear they're testing some of them as we speak.

I say poppy-cock! I don't know about Russia/China the US has the ability to track bombers from space. A while ago there was an effort, akin to GPS, to place radar equipped satellites in space around the globe - but was cancelled by politics. What nation wants somone in "Florida" to know in real time what flying over occupied Tibet? Higher flying objects are easier to detect, plain and simple, I used to work with CCD imagining hardware back in the 1990s, and it was amazing even then.. Now CCDs are better, electronics have lower noise levels, and SOFTWARE algorithms (along with OOP and better multithreading and multicore) For forward 20 years, and unless the bomber;s skin temperature is that of the surround atmosphere (+ a few degrees), it CAN be seen. Stealthy aircraft like the Raptor and Lightining II make use of the fog of war in batter.... A lone bomber with a few decoys /and over 50k feet is en entirely different matter.

Those sholder fired missiles are golden bb's. Fly a straight in and stright out mission is nutso (per Fonzie). This aircraft is going to fly in at night, and there those types of shourlde fired weapons are 1/100000 likely of taking down a poperly planned mission. We're not going to fly straight over Hinh Koing at 600 ft weaving through the skyline. Most of the world is sparsely poplulated and there ain't going to be someone with a should fired missile spead out over over every 4 square miles of terrain. That's nutso. And the bomber will have countermeasures (not just flares) to deal with those exceedingly rare and very brief glimpses of the aircraft. Ordinary night field vision goggles are useless to a guy with a shoulder fired SAM...... One last point, our ALCMS are all low flying... ie flying low mission profiles, which some seem the think is the riskiest mission profile of them all for a fast move LO aircraft. Damn, our cruise missles are all going to get taken down by AAA, ak-47s, and shoulder fired missiles.... Damn, all of the low flying anti-ship missiles are missing the point as well. Ok, let's go back to 1959. Smile
....Until we have a "bomber" that has something like low orbital flight abilities, high altitude flight is like walking into Giants stadium butt naked. Again, fighters are a different story because its a battlefield environment, and not a lone bomber flying deep into bad guy airspace.



A tracking Satellite in geo-sync orbit is a completely different deal than a LEO satellite. Geo-sync orbit is 22,000 miles and change compared to most LEO satellite being 200 to 500 miles away. Obviously, most tracking satellites are of the LEO variety and communications sats are often of the Geo-sync variety, since being 50 to 100 closer sorta makes a big difference.

So, shooting down a geo-sync orbit satellite should not be compared to shooting down a LEO sat. Also, to have continuous and reliable coverage using LEO sats requires a network of sats....which, other than a magnitude difference in cost and complexity, will still have predictable orbits that can be used to estimated areas of lower exposure. Other factors like weather can will still affect this defense.
One other misconception on satellites worth mentioning , is that while computing power is growing in leaps and bounds from commercially available hardware, this is different stuff than what can be sent up in space. Hardened chips are at least several generations behind due to the low volume/demand for them and the testing involved. This requires more than a box of depleted boron isotopes... and if you can get this or anything else that is heavier but it's expensive fast as launch costs are still around $15,000 a pound.

In the end however,I don't think the mission dynamics will be the deciding factor. I believe the words of Robert Gates when he was still Sec of Def (I'm paraphrasing since I don't remember exact quote) when he said the NextGen Bomber would likely be sub-sonic because supersonic programs and aircraft are much more expensive.

Now, if NorGrum or LockMart can believably propose a supersonic concept that isn't that much more expensive than the sub-sonic version and doesn't compromise other probable mission priorities (I'll guess this would be, Low Observable, Range, Sensors, Battlefield Integration, Maintenance, Logistic Footprint, Endurance, and Project Risk to name a few) then maybe it has a chance.

The main advantages I see in the supersonics dash capability more so than to counter interceptors would be a to reduce the amount of time command and control has to identify and react to the threat and the reduced engagement zone of defense systems since more energy is required for interception. Additionally, a difference in both of those factors will multiply the effect on each. These same factors will also make stand off weapons more effective in terms of kinetics and detection.

Other factors such as response time support strikes for ground forces will be improved but chance of this having a pivotal in the outcome of the engagement is unlikely. As for increased defensive capability against interceptors, support aircraft and other systems that maybe be in use at the time (such as long range anti-aircraft missiles/munitions and sensor jammers) would be factored into the strike package and the speed of strike aircraft will determine the application of. Increased speed of the striker would possibly reduce the demands on these resources but not eliminate the need of, so not a big risk or cost reduction there.

So, to sum up...a couple of distinct capability advantages to being supersonic, but it's all boils down to the monetary and design costs of doing so. If the past we've shown that we're willing to pay dearly for capability, but the appetite for doing is probably reduced in the current political environment...and if making it supersonic makes it less versatile...then that follows the same design problems had the B-70 and B-1.

Anyway, I rambled on enough....just wanted to clear up the statements about satellites.

Just in time to provide the "answer" to the Pak-Da which is now slated to rollout in 2020.

But what are the Russians going to do about the Pak Da? There isn't any time for them to copy the design? They're going to be left with copying a 30 year old B-2 design!




Russian officials have already rejected the idea that the PAK DA will be based on the B-2, and what do you mean by "What are the Russian's going to do", are you applying that the Russian's can't come up with their own design?

Well see about that Laughing

Recently as 3 years ago, US officials and fanboys were still saying that F-22 and F-35 will not be challenged for next 20 years LOL remember that because I do, so if I were you I would not be so sure.
