Apparently the late WW2 Soviet Joseph Stalin III (JS3) mounted a huge naval 122mm gun. One of the most gripping wartime books I ever read is the Last Panther by Wolfgang Faust. It tells a personal and brutal account of the 9th Army breakout from the Halbe pocket - in it the author's Panther is confronted by a JS3 but the JS3 having missed with its first shot has to bring its naval gun down to the horizontal to reload, whereas the Panther reloads its standard 88mm faster and is able to get in the killer blow.As far as I am aware there has never been a lot of commonality between naval and land guns. Navies and armies doing their own thing - inter-service politics and all that. Also, I believe that naval guns have a higher velocity. A 127 mm naval high velocity gun on a Leopard II would be a nasty piece of work.

I guess I can add to that. But just art work.

The public is finally getting a look at all of the contenders for the US Army Next Generation Squad Weapons program
Prototypes For Army's Next-Gen Squad Weapons Finally Revealed
General Dynamics (GD-OTS) common platform bullpup entries (auto-rifle top) and their 6.8mm composite cartridge
Of note, reporting is that the auto-rifle sports a 22 inch barrel, while the carbine's in 20 inches
Sig Sauer's AR and carbine entries and their 6.8x51mm hybrid cartridge. (In my view, easily the lowest developmental risk offering)
Sig's AR features a 16 inch barrel, while the carbine's is only 13 inches. (I'm assuming to make weight limits)
Textron's cased-telescoped ammunition entries.
(I wasn't able to find a decent image of the 6.8mm CT round. But given that the developmental 7.62mm & 6.5mm rounds shared casings, I would expect the 6.8mm to be similar)

Another range upgrade. This will be a significant range and lethality upgrade for dismounted Infantry units
doubleing range of the Javelin from 2.5 out to 4.5km will be significant

...and on that note;
Raytheon, Saab conclude initial guided flight trials of Guided Carl-Gustaf Munition | Jane's 360
I imagine this could be quite transformative for the weapon, and dramatically improve the range at which it can effectively reach out and touch enemy armour.

If I were to guess, I would assume this is part of the test program of the CH-47 powered by the CH-53K's GE T408 engines
While I am intrigued by the possibility of a CH-47 with significantly increased lift capacity and airspeed. I also have to acknowledge the likelihood that increase of performance will include the drawback of increased fuel consumption. As they have basically maxed out available fuel storage space in the Block 2 fuel system modifications, they're either going to need make some serious structural mods, or accept reduced range/operating times

Could they put saddle tanks on it forward of the engines?

Given that for several decades no one has attempted such an application, and instead loaded various internal auxiliary tanks, I would have to assume such a choice would require numerous airframe structural modifications to support the load forces the aircraft was never designed to bear.
I would add, that the once planned CH-47F Block 3 upgrade, that included improved performance capacity with the future affordable turbine engine (FATE) program, included the prospect of a lengthened fuselage. I would guess that included the insertion of larger fuel tanks.
Edit:
Lest we forget, they have stretched the -47's fuselage before.

According to this article a re-engined chook with the General Electric T408 may have longer range and be cheaper to operate than the current F models. Boeing were somewhat hesitant to give any details.

More news on the new personal and squad weapons systems that the US Army are investigating and hope to introduce into service in the next 4 years. Definitely some interesting weapons there. I do like the 6.8 mm calibre - far better than 5.56 mm IMHO. I've always regarded 5.56 mm as to light.

The Canadian variant of the CH-47F has extended range tanks. This extra capacity is pretty obvious in the photos below.

Those girls certain got some hips on them.. Good to see they already have structural design mods on the books for increasing fuel capacity
Yes, nice hips indeed. You can see the difference even better in the two photos below, the first being a "standard" F model (tan), and the second being the Canadian variant, CH-147F. The extra tankage doubles the range. A re-engine of this variant (either the new version of the T55, or the T408), with the new composite rotors, would be quite a leap in capabilities, and would, in my opinion, breath new life into this formidable helicopter.

The US army is getting a new engine for its current and future IFVs. Developed by Cummins, it is a compact 2-stroke design with advanced emission controls, high output generator, and new transmission. It’s compact design means future vehicles can be smaller volume and thus less armour will be required. Also, the 1000 hp unit can scaled down to 500 hp or up to 1,500 hp.

Major jump in ATGM range for light infantry forces in the US with the development and soon fielding (2022) of a new Javelin with ranges out to 4.5km(previous 2.5). THis will be a significant all weather advancement for light battalions that are easily deployed in their fight against enemy armored vehicles. New unit will be all weather and 30% lighter than the current model

Shocked. Shocked I say.
The US Army has cancelled the latest Bradley fighting vehicle replacement program, the Optionally Manned Fighting Vehicle (OMFV)
As most will recall, only General Dynamics successfully submitted a qualified bid, after Raytheon-Rheinmetall team's Lynx offering was rejected after being unable ship their sample vehicles to the US on time.
