1- Speed doesn't matter on shaped-charge munitions. As long as the force is sufficient enough to set of the fuse, it will penetrate.

2- The only armor the switchblades will be dealing with is the top turret armor/engine deck. That is sufficiently thin enough for the Switchblade warhead to penetrate, especially the Switchblade 600 which carries a Javelin warhead.

look forward to pictures of results.

Seems with such tech now one would want to be a dismounted infantryman over any vehicle these days. No wonder they are having to come out with TROPHY and such. Just the never ending countermeasures and expense of any system.

The B-52 may have a lifetime that exceeds the C-47, and I didn't think that was possible. Their usefulness in contested airspace has been pretty iffy for decades, but standing off with cruise missiles makes it a whole different ballgame.

Right in your wheelhouse though..KISS..lol.
They should keep using steam gauges on the beast. Hell, probably only aircraft that could really survive, launch and return in an EMP battlefield. Do not trust Faraday cages to protect a flying computer. Hell the F-22 crossed the International Dateline decades ago and had to abort mission because the freking programmers forgot it.

The AF has a contact with Rolls-Royce for new B-52 engines. Apparently they are engines already in use and were selected because the will fit within the current nacelles.

Yea..I read an article a couple of weeks ago and for years they talked about 4 turbofans instead of 8. Engineering is not as simple as sticking something onto something. Wish I could find it and I would link it.

I saw a list of current US AF fleet and I believe the B-52's are still in service near term. At least, enough that other countries would want engines. There are not a lot of B-2's (only a handful). IMO the entire AF is due a re-evaluation of air craft. We should have the latest and greatest. We are known for air superiority. The problem is everything is going UAV. Drones are taking over. AI flown dedicated robot aerial fighters are right around the corner.

I don’t think you understand the definition of oligarchy if you think they are similar but you do so clearly you don’t. You are also having a difficulty with ethnicity and nationality. Are there very rich people in the US? Absolutely. Do they run the US government? No, they don’t. Can they buy influence because they are wealthy? Absolutely. Is that the same thing as a handful of very powerful families actually running the government while the majority of people live in relative poverty? No, it isn’t, not even close otherwise every major developed nation on the planet is an oligarchy. China, Russia, and a handful of Middle Eastern nations are prime examples of oligarchies. You social studies teachers failed you.

It's an issue with an undersized rudder for a 4 engine configuration.

A B-52 losing one of 4 engines will create too large of an asymmetric thrust for the existing rudder to counteract. Control can still be maintained when losing one of 8 engines with the existing rudder.

These two articles make it sound like they are going with the eight engine design; I'd wondered about whether it would be four big fanjets. However, if they are using an engine that's in the C-37, it has to be eight.

That was my point. Dont fix what isn't broken. The article was why they did not go 4 engine.

I dont think people understand that what we are witnessing is war at a new level of psyops. Can you imagine if everyone of our soldiers in Iraq who died, their family was contacted by al queda before the family even knew they were dead? Granted, it wouldnt happen with USA much since we famously "never leave a man behind" but still.

I think we are going to see war waged here in ways that redefine the "information age". My concern is that Russia decides to go back to the old ways and simply bomb things to oblivion. Nukes are not needed. they could do a lot just running bombers. Second concern is that since this is the first time modern major states are going to war with each other (via proxy), we are seeing it evolve with new methods that will outlast this conflict.

My dad told me years ago that he and other fighter pilots attending an airshow stamped "An unmanned missile will never replace the manned interceptor" on a bunch of missiles on display. The AF also decided several times over several years that guns were obsolete on fighters ... and proven wrong several times. I think the AF really screwed up in making the AF Academy a place for pilots only; you really need a mix of engineering types tied closely with pilots to develop the next generations of planes - you start that relationship in places like universities. My brother is a retired fighter pilot and I'm an engineer; it's interesting when we discuss stuff with our different backgrounds how it changes the overall understanding. We communicate in a way that seems to be missing when the AF is trying to develop new planes - one group going one way and the other wondering WTH because they don't seem to be on the same page.

Russian forces continued small-scale, tactical attacks on the Izyum and Severodonetsk axes; additional reinforcements to date have not enabled any breakthroughs of Ukrainian defenses. Russian forces continue to deploy reinforcements to eastern Ukraine but show no indication of taking an operational pause. The Russian military appears to be carrying out an approach in eastern Ukrainian similar to its failed efforts north of Kyiv in early March—continuing to funnel small groups of forces into unsuccessful attacks against Ukrainian defensive positions without taking the operational pause that is likely necessary to prepare for a more successful offensive campaign. Russian forces continue to grind down Ukrainian defenders in Mariupol, though ISW cannot currently assess how long these forces will hold out and their current supply status.

Key Takeaways
  • Russian forces continued to grind down Ukrainian defenses in southwestern and eastern Mariupol, though ISW cannot confirm any major new territorial changes in the past 24 hours. Ukrainian defenders reported that the situation is “deteriorating” and Russian forces are deploying additional artillery and heavy weapons.
  • Russian forces continued unsuccessful daily attacks against Rubizhne, Popasna, and Marinka and heavy shelling along the line of contact in eastern Ukraine.
  • Ukrainian forces repelled Russian attacks from Izyum toward both Slovyansk and Barvinkove.
