US Army News and updates general discussion

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. :D
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.

Couple of items on US Army FARA (Future Attack Reconnaissance Aircraft) contenders.

The Bell 360 Invictus

The AVX Aircraft - L3 Harris coaxial rotor helo
I guess I can add to that. But just art work.
Boeing still leaving everyone guessing

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
GD-NGSW and TV 6.8.jpg

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)
Sig-NGSW and 6.8 hybrid.jpg

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)

I'm not sure how I feel about the bullpup options. I have never used one, but I can't imagine it works well for speed-reload.

Video on the Bushmaster 50 mm chain gun for the US Army New Generation Combat Vehicle.

Add the video of fire testing on 50mm Chain Gun. Upping the Calibre of IFV seems also happen with Russian where they are modified S60 based 57mm AA gun.


Put this just as simple comparison.

...and on that note;

Raytheon Missile Systems and Saab Dynamics have completed an initial series of guided flight trials of the developmental Guided Carl-Gustaf Munition (GCGM) - the first guided round for the 84mm Carl-Gustaf reloadable weapon system. The trials pave the way for an end-to-end GCGM System Capabilities Demonstration in the United States in the spring of 2020.

Jointly funded by Raytheon and Saab, and intended for use with the Saab Carl-Gustaf M4/M3E1(A1) Multi-role Anti-armour, Anti-personnel Weapon System (MAAWS) launchers, the GCGM development is effectively an evolutionary progression of the earlier Saab Dynamics Ultra Light Munition (ULM) concept, which, under a teaming agreement signed with Raytheon in November 2017, has been matured and defined in terms of capability and performance requirements.

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.

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.
US Army Cancels $45B Armored Vehicle Contest That Drew One Bid
The U.S. Army said it would reevaluate its effort to replace the Bradley Fighting Vehicle after just one company submitted a qualifying bid in the $45-billion contest.

“Based on feedback and proposals received from industry, the Army has determined it is necessary to revisit the requirements, acquisition strategy and schedule before moving forward,” the Army said in a statement released Thursday afternoon.
