Was around a B-1 unit for a few years right after it got it's Block D.
Some fun things in no particular order...
Block D is what really gave it huge
practical conventional strike ability. This gave it the ability, for the first time, to have 24 JDAM (GBU-31 series) in it. The radar could on the final bomb run do "enhanced" coordinates that when pumped into the weapon on the rack before release helped get some dead scary accurate bombing with JDAM.
-Maintenance hog as mentioned. When then Sec AF Roche* announced that the B-1 fleet was going to be downsized back in circa 2001, part of the plan was that the savings in sending some to the boneyard would pump savings into upgrades for the aircraft, Block E etc etc. Like a lot of downsizing promises like that, the budget dollars rarely appear. Of course later USAF dragged more out of the boneyard and put them in service in a fast reversal of that decision. Maintenance on the aircraft has always been severely underfunded by USAF. Many would look at unit readiness rates that would get down to 51% and really tack on the maintenance hog label. The rest of that story not too long ago as told to me by a B-1 program manager was that USAF was funding B-1 maintenance circa 2001-2 at around 49%. That means on the average, the maintainers, through a lot of sweat and hard work, ( and "can" birds ), added that 2%. The ones I saw were always busy but loved the aircraft for what it was... I mean those in the community can always claim by video... that it is the only heavy bomber in service to do a roll at the top of a climb in a demo at an undisclosed location.
Powerful and impressive and given that we are only losing more and more overseas bases, big bombers become more and more important.
Best mods to make a big difference in improving maintenance up times ( besides proper funding) are to replace most of the legacy cockpit avionics, and flight controls. This really would help. Wish we had the funds.
AFAIK the first aircraft to use the ALE-50 in combat in the ex-Yugo region some years ago. At the time of the event there was only one jet that had it on it.
The Sniper-XR being put on the aircraft will be a big help for the bug hunt type of wars we are doing now. Being able to self designate lgbs will be handy.
This aircraft currently is nice for CAS. It zips out of the JSTARS stack pretty quick, carries a lot of gas and weapons and can hang around until the JTAC is happy. Makes some loud show of forces passes too when that is needed. "Speed" in response to 911 JTAC calls means something for the guy on the ground eating dirt. A B-1 or F-15,16 etc that shows up in 10 minutes or less beats an A-10 arriving much later. Time is blood. AC-130 isn't a 911 response aircraft but a kill box interdiction at night aircraft including pre-planned ops.
Also re: big bombers and CAS. Once things like F-22, B-2 etc beat down large SAMS and enemy aircraft all the rest of the legacys can drop PGMs that are in much use today like, JDAM, LGBs, CBU-105, JSOW etc from 30-40,000ft, and small battlefield SAMs, MANPADS, AAA and trashfire aren't going to do anything. I can touch you but you can't touch me. In the shooting fish in a barrel phase where ISR helps B-52,B-1, F-15~18 etc etc... plink heavy equipment,AFVs, Arty, ground equipment, logistics... no problem. Also JTACs routinely work with these platforms no problem and get the support they need. Again where the U.S. is losing more and more foreign base options, long range bombers are it if the carrier can't do it or isn't around. No B-52s need to be retired and B-1s need the upgrades I mentioned. All of that is good value. Also an "either-or" argument of B-52 and B-1 isn't especially useful. At this moment in our time we need the total number of large bombers we have. The obvious rings true that there are only so many B-1s and so many B-52s. It is having the total number of them on hand and not so much their different performance ability that makes up the firepower value. If it were a perfect world then that would be a different story. However right now for the USAF mission, big bombers offer much more total value then a new small single engine fighter that we can not afford partly due to so many funds going into a war paid for with the credit card.
*Sec AF Roche when after announcing the initial B-1 to the boneyard thing in 2001, got a new nicknames from the B-1 community. Some not printable here. One was Jabba-The-Hut.
