The JASSM-XR is certainly a strange design compared to the standard JASSM especially with the Canards.

What's the history on this? Is it the original ER? Is it a newer concept? ???

edit: Here we go: http://www.flightglobal.com/news/articles/sure-strike-209026/
 
Love the last two paragraphs:

The demonstrations proved that JASSM has the potential to open up new ways of dealing with cave targets: "This thing flies inside. It gets its nose inside and throws all that [blast] over-pressurisation down there and around corners... In this test we instrumented downstream to see what over-pressure and under-pressure results we might be able to get with this warhead. We even had some detectors and sensors outside and it kind of did a big job. Not just here [in the cave],but the whole surrounding area had some impact to it.

"I believe that if you dig a tunnel like that and build it to whatever your people tell you to build it to, you will believe you are safe. This will tell you that 'maybe I ought to go and find a new hole'

Anybody know any details about it's physical characteristics?
 
Just this one page. It doesn't give sources for this, though, so take with a grain of salt.

Lockheed Martin is now working on an improved wing design for the JASSM-ER that will "significantly" extend its range, though no details have been announced yet. The company has considered a "JASSM-XR (Extra Extended Range)" variant that would double the range again to over 1,600 kilometers (1,000 miles), but would only be carried on bombers and heavy strike aircraft. The JASSM-XR design would be stretched to 6.3 meters (20 feet 8 inches) and feature a fixed canard to ensure flight trim. At the other end of the scale, the company has considered a shortened variant, the "JASSM-SR", that could be carried in the internal weapons bays of stealthy strike aircraft.

Wait, here's the source, originally in Flight International. But it's from 2005, so that version of JASSM-XR might be quite different from the current one.

https://www.secretprojects.co.uk/forum/index.php/topic,6727.msg56825.html#msg56825

Development of the more than 1,850km-range XR cruise missile is continuing apace, with Lockheed revealing it began windtunnel testing last February with a 5% scale model of the JASSM derivative. With an overall length of 6.3m (20.8ft), compared with the JASSM-ER’s 4.2m, the XR features a fixed canard foreplane and folding main wing. The canard is required to ensure the single turbofan-powered missile maintains a stable flight profile and to compensate for the weight of the Lockheed-designed 540kg warhead. Bigum says the design “preserves the low observable characteristics that we have brought in from the JASSM, even with the canards”.

Detailed concept work began in early 2004 with the aim of providing an alternative means of engaging and destroying hardened and deeply buried targets, with the company-funded development now being pitched as a potential new-start USAF ACTD for fiscal year 2007. About 80% of the JASSM design’s electronics would be reapplied in the basic XR missile, although Pappafotis says the project provides an opportunity to explore alternative warheads, datalinks, non-co-operative target identification technology and precision guidance systems with reduced reliance on GPS. The missile would not use a terminal seeker under current concepts, instead receiving target updates from USAF Northrop E-8 JSTARS aircraft via datalink or satellite.

The weapon’s rocket-boosted penetrator warhead will have a velocity of about 2,300ft/s (700m/s), says Pappafotis, who adds that the charge will be “going in [at] better than Mach 2”. If fielded, the XR cruise missile would be carried by the USAF’s Northrop B-2 and Boeing B-52 bombers, which, respectively, could carry up to eight and four weapons internally and two and eight weapons externally. Boeing’s F-15 fighter is another possible candidate host platform, says Pappafotis, with the type viewed as a potential trials aircraft if the proposed ACTD gains approval.

If they ditched the fixed canard it would be a perfect Tomahawk replacement/complement in the Mk41 VLS. (Swap out the VL-ASROC Mk114 booster for the Tomahawk booster.)
 
It might be too long for Mk 41 -- 6.3 meters without booster is already as long as Tomahawk with its booster (~6.28 meters). The booster adds a bit over 0.7 meters, which would make JASSM-XR "Naval" close to 7 meters total. That's longer than SM-6 (6.6 meters) or any other inventory weapon. It's slightly shorter than the Mk 41's max canister length (7.18 meters) but there may be issues with internal clearances there.

Once upon a time (about 2006, so just after the artciel above), they were talking about another notional missile called Cruise Missile XR that was basically a large JASSM derivative somehow distinct from JASSM-XR.

https://www.flightglobal.com/news/articles/sure-strike-209026/
 
Lockheed Martin is also continuing to refine its concept for the 'extreme-range' JASSM (JASSM XR) that it envisages with a range of more than 1,000nm and optimised to defeat hardened and deeply buried targets via a boosted penetrator warhead.

Pappafotis said the company expects to conduct wind tunnel testing later this year of this variant, which only bomber aircraft will be able to carry due to its size and weight - up to three times as heavy as the baseline JASSM. B-2A and B-52H aircraft would be able to carry four XRs per rotary launcher, he noted.

The company hopes to receive air force sponsorship for JASSM XR in 2006. It is already under contract to build the JASSM ER, an extended-range variant that is the same size as the baseline missile, but has a range of around 500nm, more than twice the baseline system's.

Despite the Mini JASSM concept, Pappafotis said the company is still examining options for integrating the baseline JASSM externally on the F/A-22 and F-35. "We think there is value in pursuing both and we are continuing to do both," he said.

If they stretched it that long that's AGM-86B length. And only a 1000 miles? I'd think they'd get much more range with that much of a stretch.

CALCM apparently has much less range than the nuclear ALCM (600 nm "nominal" per the official fact sheet, but the actual is classified). The big conventional warhead eats into fuel pretty dramatically. If JASSM-XR is hitting 1000+ nm with a large hard-target penetrator warhead, that's nothing to sneeze at.

They provided money for the new wing last year. It's possible this is a continuation, but you'd expect there to be some indication of that, wouldn't you?

http://www.airforcemag.com/Features/Pages/2018/September%202018/Lockheed-Martin-Developing-Extreme-Range-JASSM-Variant.aspx

A Lockheed Missiles and Fire Control spokesman said the new version is "part of a planned upgrade" of the JASSM "family of missiles"
which includes the baseline AGM-158A JASSM, the AGM-158B JASSM-ER, and the Long-Range Anti-Ship Missile AGM-158C.
The Air Force could not immediately say if the most recent variant will carry the designation AGM-158D.

The upgrade includes a new missile control unit computer, "which will support the other planned capabilities," the spokesman said.
These include "new wing designs to increase standoff range through aerodynamic efficiency, and a new GPS unit to
further advance our level of protection." The Air Force will acknowledge only that the JASSM-ER has a range in excess of 500
nautical miles, so the XR's range will presumably be greater.

Ok, so it sounds like this is the new wing JASSM-ER, rather than the old stretched XR Lockheed was offering a decade ago.
 
The Flight Global linked story indicates the 2003 privately funded Lockheed program for long range Cruise Missile XR program would be for all three services, leveraging JASSM technology. Its also described as being a large missile for large platforms including surface ships, submarines and heavy bombers. This is the kind of program that might be revived in light of the Chinese A2/AD missiles crisis for the Defense Dept and a complete lack of very long range missiles that can be launched without entering the Chinese A2/AD zone around the first island chain and hypersonic glide weapons launched on DF-21 missiles. Its this kind of missile that might also be at the center of the Chinese hacking story of a secret "supersonic cruise missile" program in the Pentagon. If it has a final supersonic attack stage, like a Kalibr cruise missile, this could be a game changer in the how the Chinese would have to adapt their anti missile defenses for the fleet.
 
Still no word on the AGM158D? Even though, allegedly, USAF is already ordering the first batch this year?

We still don't know if it will be meaningfully heavier or longer than the C variant?
 
Supposedly the JASSM-XR is now the JASSM-ERB2.

AGM-158B2 will be the next variant in the line of JASSM-ER missiles. The USAF is expected to begin procurement of the JASSM-ERB2 beginning in Lot 19.

Revealing the decision in the fiscal year (FY) 2022 budget request, the navy will instead procure a variant of Lockheed Martin's AGM-158B Joint Air-to-Surface Standoff Missile Extended Range (JASSM-ER) cruise missile to meet both strike and offensive anti-surface warfare (OASuW) requirements. This so-called Navy JASSM will also leverage from the AGM-158C Long Range Anti-Ship Missile (LRASM), itself a JASSM-ER derivative.

initially the Fleet in to opposition Air Force (which love JASSM) was throw money into Boeing and his SLAM-ER, then struggled with obsolescence, later give rise JSOW-ER and dropped it and finally come to AF first choise :D

The AGM-158D is to big to fit into the Common Rotary Launcher. The LRASM is 500lbs or so lighter. I am not sure if it fits. I found your forum searching for LRASM information.

Hello everyone my first post from the USA.
 
For long range strike missions. I think hypersonic weapons will take over. It will start out with one or two primary systems and branch out into specialized systems. The AGM-158D is to big to fit into the Common Rotary Launcher. The LRASM is 500lbs or so lighter. I am not sure if it fits. I found your forum searching for LRASM information.

The US Just Revealed a Secret Airborne Test of a Long-Range Cruise Missile
The December test was part of the effort to equip B-2 bombers to fire the stealthy JASSM-ER.

The U.S. Air Force secretly test-fired a long-range variant of a stealthy cruise missile from a B-2 stealth bomber late last year, defense contractor Northrop Grumman revealed Thursday.

The disclosure of the December 2021 test comes amid increased tension between the United States and China. Beijing conducted military drills and ballistic missile launches near Taiwan after high-profile visits to the island by House Speaker Nancy Pelosi and other U.S. lawmakers.

The cruise missile—Lockheed Martin’s JASSM-ER—has about triple the 370-kilometer range of the standard JASSM, and is slated to be retargetable in flight, making it easier to hit mobile targets deep behind enemy lines. The variant has already been fitted to the B-1 bomber and F-15E strike fighter.

“That's a real advantage to be able to conduct strikes in any direction, if you will, and at range,” said Mark Gunzinger, a retired Air Force B-52 pilot who directs future aerospace concepts and capabilities assessments at The Mitchell Institute for Aerospace Studies. It also “expands their ability to avoid the highest-risk threat areas while still holding the targets at risk.”

Few details of the test were revealed. The “B-2 successfully released a Joint Air-to-Surface Standoff Missile – Extended Range,” Northrop said in a Thursday statement. Air Force officials confirmed the test occurred, but did not immediately have additional details.

“The JASSM-ER further enhances the B-2’s ability to hit any target, anywhere,” Northrop said in the statement. “The integration of JASSM-ER enables the delivery of a low observable asset capable of traveling greater distances than its predecessor

The B-2 is already certified to fire the standard JASSM cruise missile, according to the Center for Strategic and International Studies. But the -ER version adds range and, eventually, retargeting in flight.

“The JASSM-ER will eventually incorporate a weapons data link … into the missile allowing for course corrections after launch,” the think tank said. “This is a critical upgrade for road-mobile and maritime targets.”

The Lockheed Martin-made cruise missile, called JASSM-ER (pronounced jazz-um), is designed to evade missile defenses and can fly more than 500 miles. Until now, the Air Force has focused on installing the missile on its non-stealthy aircraft, including the B-1 and B-52 bombers and F-16 and F-15E fighters, according to Pentagon budget documents. This would allow those warplanes to strike targets inside enemy territory without having to fly close to those targets. But installing the weapon on the B-2, a stealth bomber already designed to fly undetected into enemy airspace, would allow it to strike targets even deeper inland.

“Having a penetrating capability with extended range—it expands the options for strikes available to our commanders,” Gunzinger said.

While it takes time to assess the results of a weapons test, he said they are usually ready much quicker than nine months after they happen.

“Frankly, I find the timing interesting, let me just put it that way,” he said.

If i remember it right AGM-158D is now XR? So it is said to have a new wing Design. Has someone any information on that?
 
The wing mod was removed from the program several years ago, the D variant is an electronics upgrade to the B-2 variant integration a weapon data link for in-flight retargeting. AGM-158D's official name is still JASSM-ER.

Earlier plans did include integration of a new laminar flow wing onto the JASSM-ER design that would increase range by an undisclosed percentage, though certainly not to the 1,000 nmi number you see bandied about on the internet.
 
Nah that im sure but based on the range increase from jassm which was said to be 3x 370km so 1100km ish and to that maybe some 15-30% more is an big increase. With 30% you should get around 1430km....
 
The recent JASSM-XR effort was never stated anywhere to provide that range increase, in fact nowhere had the USAF ever provided any estimate of increase in range over the ER. Claims from crappy outlets like TWZ that the XR would have massively increased range and a 2,000lb warhead are taken from a twenty year old LM proposal that amounted to a totally different weapon.
 
I know. But based on what is known of ER which is Said to be 3x 370km (1.110km) i think Wiki has ~930km? 10-30% more and we are by around 1221-1443km (Wiki:1.023-1209km).
Increase is increase even if its not the unrealistic ~1900km with a 1t warhead.
