JASSM was allways 25.3 in wide. Neither B or C changed that. For some reason i can't find the factsheet on AF.mil anymore but they also stated this under there pictures:

AGM-158 Joint Air-to-Surface Stand-off Missile (JASSM). GPS/INS-guided air-to-surface powered missile. Dimensions: Length 14 ft., width 25.3 in. Range: more than 230 miles. Image created by Billy Smallwood of the Air Force News Agency and is 8x2 inches @ 300ppi.

So where did the 22" number come from?

And where TF did Wikipedia get it? Janes? Who here has a Jane's subscription?

Wiki is currently saying that the AGM-158A has a 22" width, while the -B has a 25" width.

That seems weird to me, why would you change the OML like that and then say "Using a more efficient engine and larger fuel volume in an airframe with the same external dimensions as the JASSM, the JASSM-ER is intended to have a range of over 575 mi (925 km) compared to the JASSM's range of about 230 mi (370 km)." (emphasis mine)
 
For reasons at hand I'm not going to discuss this any further
but there are two key informations you don't know or figured or found out yet.
The wings are different.
The wing spans are different.

Yes wasn't that this laminate flow wing ? I remember the discussion we had here quite some time ago. While i can see how this could lead to a larger width but i stay by my statement that it allways was around 25 inches.

Around 0,3m more tho if this impacted the diameter?

Between LRASM and JASSM?

I assume more lift while reducing drag, hence, chord length got longer which increases folded width.

Between A-JASSM and B-JASSM-ER.
It looks like one site still has the old data recorded and not fixed-aligned like with most everyone's copy paste or falsely-assumption-autofixed-it etc.

Shows longer wingspan, not wider stowed wings.

here's a screenshot from a site by a group of navy ex-militaries "highlighted the relevant part" ;):

And where is that on the site you linked? Because all I'm seeing is this:

I’m wondering whether different production batches of JASSM might use slightly different formulations or modified versions of AFX-757.
For example, could there be changes in the composition, material quality, or other adjustments between batches?
I would also be very interested in learning about any explosive iterations in other missiles that use AFX-757.

There is a more powerful explosive known as AFX-777 but I don't know of any missiles using it.
 
A notice of intent released on Friday indicates that the U.S. Air Force plans to procure over 11,000 JASSM and LRASM missiles over the next five to seven years, significantly raising its inventory targets—targets that have been steadily increased over the past decade.

Procurement of JASSM will remain at high levels in fiscal years 2024–2025, with slight adjustments in 2026 due to budget and inventory considerations. A breakdown of projected JASSM and LRASM procurement for fiscal years 2024–2026 is provided below (based on publicly available budget and contract data).

Thanks, I had not realized LRASM was being purchased at that level. Still low, IMO, but there should be many hundreds in inventory by now.

Last I heard, production per year had increased to 750 with a goal of 1100, and those numbers must be out of date given USAF goals.

uhm.

We're 3/4 of the way through FY2026. What the heck is up with the future tense?

11,000 in 5 years means an average of 2200/year.

A GE Aerospace and Kratos partnership will become a second engine supplier for the Lockheed Martin AGM-158 Joint Air-to-Surface Standoff Missile (JASSM) family, backing up the Williams International F107 with the newly designated F143-ZZ-100 turbofan.
