Army inks Iron Fist buy for Bradley fleet, after years of budget delays - Breaking Defense

“We were able to find some efficiencies [in the supplemental] that allowed us to buy small quantities of Iron Fist,” Maj. Gen. Glenn Dean, the service’s Program Executive Officer for Ground Combat Systems told Breaking Defense.

Maj. Gen. Glenn Dean, the service’s Program Executive Officer for Ground Combat Systems, said that the Army managed to move money around that will allow the service to finally equip the Elbit Systems-produced Iron Fist Light Decoupled (IF-LD) onto a handful of Bradleys, but cautioned that the total procurement is more in the “dozens” than fleet-wide.

For years the service has been hunting for APS’ to integrate onto M1 Abrams main battle tanks, Bradleys and Strykers to protect soldiers inside from incoming threats like rocket propelled grenades and one-way attack drones.

Although some Abrams and, soon, some Bradleys will have APS protection, Strykers remain without a candidate. Last year the service completed limited characterization testing with a possible candidate called StrikeShield, a hybrid hard-kill and armor solution by Rheinmetall and its US partner Unified Business Technologies, but that didn’t prove to be the right solution.

“We don’t have a suitable solution,” Dean said today.

Which brings me back to the 30x113 mm Chain Gun as a replacement for the Vietnam Era 40-50 combo as originally deployed on the Cadillac Gage Grizzly turret.

The 30mm round is large enough to accommodate the low cost radar and optical sensors being employed by the car industry. That makes the MMPA and HEP rounds possible.

US Army developing new smart munition for M-SHORAD chain gun

The US Army plans to start development in 2024 on a munition that can be programmed to better take out small unmanned aircraft systems (UASs) and ground vehicles targets...

To my way of thinking, given the proliferation of aerial threats replacing ball with proximity fused rounds makes sense. The 40 mm could do that but its low muzzle velocity doesn't assist accuracy or engagement ranges.

Thus:

30x113 mm is the compromise for when you think 100% of your lighter vehicles always need both .50 cal and 40 mm AGL.

I think this is especially true if you don't have access to something like the Iron Fist / Trophy APS type systems.


Taking the 40s and 50s away from the Strykers and replacing them in the existing RWS with the M230LF / XM914 makes sense to me, especially given that it is also being used in MSHORAD, MADIS and the Agnostic Gun Truck systems.

Could a platoon of three XM914 Strykers and an MSHORAD Stryker be netted so that the MSHORAD controlled the fire of the other Strykers?


....


WRT the Dragoon Stryker - how about turning that into an ADATS Stryker armed with either the 30x 173 round or even the 35x 228 AHEAD capable cannons like those used by Gepards, Millenium Guns and Oerlikon GDF-005s as well as the CV90s delivered to the Netherlands, Denmark and Norway.

...

WRT our LAVs - Upgrade the M242 25mm to the 30x 173mm Mk44 Bushmaster II? Will it fit or does it need a whole new turret?

IMHO, a new turret based on a Moog RIwP system that allows fleetwide tailored and retailorable solutions would be highly desirable. Not only would it provide a standardized turret system to solve a variety of needs, but it would also provide more internal space for additional ammunition or personnel in the vehicle. An added bonus would be that the system is vehicle agnostic and could be used on more vehicles than the LAV - Maybe finally a use for TLAVs.

With the recent ACSV purchase the long-term retention of the LAV fleet is a given. The next stage should be to upgrade the fleet to meet a wider capability than it has such as SHORAD and ATGM.

And to make @KevinB happy, to add a tracked IFV capability to the army which could also be fitted with the same RIwP systems - maybe rift off the Bradley chassis.

London will need something to do after ACSV

 

[FJAG]

London will need something to do after ACSV

Agreed. And switching the fleet to RIwP turrets would be useful and relatively inexpensive. I'd also like to start them on something tracked albeit I'm not fond of their tracked version of the LAV. OTOH Ajax/Ares seems to be maturing (the Brits seem to finally be happy with it in the field) and if you get rid of its strange turret and replace it with the RIwP ... maybe that would be the solution. Four battalions (for two armoured brigades) should do as a starter.

they can switch the turrets and then get working on the LAV 800 a hybrid drive common hull powertrain that can be wheeled and tracked

Yeah. I haven't been able to put my finger on it because of the scarcity of information on it, but I don't think a common hull to accommodate tracked or wheeled configuration is as common as they would have you believe. There is a world of a difference in the hull configuration, suspension and the drive train/final drive even if a common engine can be used.

I know the LAV 6.0 has become a pig in weight, but the real reason behind a tracked IFV and something like the LAV6.0 is supposed to be its armoured protection to make the tracked IFV a more combat capable machine. A tracked system and IFV requirements means more weight which means bigger engine and a bunch of knock on effects.

Personally I'd prefer to see a purpose built tracked IFV like Ajax/Ares or Puma and similar systems.

I remain intrigued by the possibilities. It might not make sense for larger militaries with large platform numbers but for smaller ones with smaller appetites or budgets?
How much of the design constraints could be alleviated by hybrid drive? I remain surprised at the lack of uptake.
Is it armour that the LAV 6 and 700 are lacking or mobility?
In my industrial applications I cant say that my tracked machines were more heavily powered than my wheeled ones , if anything the reverse. I wonder if this is a carryover from previous lighter wheeled variants

I would love to see a breakdown of the powertrain layout for the wheeled/tracked Stryker/Boxer

 

[FJAG]

It's that a tracked assembly weighs more than a wheeled assembly for the same sized vehicle and that the amount of armour needed for an IFV application is thicker and heavier than one for a medium application APC. That additional weight leads to the need for a heavier-duty engine.

I'm generally a fan of the concept of hybrid drives in civilian applications (I'm against pure EVs). But I do have reservations in a military environment. I recognize its advantages but I think these don't compensate for a heavy, complex and volatile battery brings to a vehicle that's liable to be engaged in combat and generally subject to rough handling. Watching T72s brew up and toss their turrets because someone thought it was a great idea to store powder bags and high explosives inside in an autoloader in the hull makes me wonder how much minor battle damage to a hybrid will result in a catastrophic stored energy release that turns a repairable/recoverable veh casualty into a total write-off.

We've already gone from vehicles that a driver with a tool bag could fix to ones that need a service centre with high priced electronic diagnostic systems. We need to simplify kit wherever possible.

I guess i wasnt thinking hybrid in that sense just electric drive.

Like a direct-power diesel electric or like a battery-storage petrol electric?

I've always liked the former but have doubts about anything that involves large storage batteries. I think pure EVs or ones designed for significant pure electric operation are a very good option for recce motorcycles and very light weight recce vehicles but an unnecessary complication for anything heavier.

The first. It is proven technology for ages and should free up lots of design considerations. One might need something for "quiet" mode batteries or an APU

To stick with GD, if we want tracked, let's Frankenstein this. Give me the M10 Booker chassis, then let's stick the LAV MSHORAD turret into it, or the LAV 6 Recce suite.

The M10, like the AJAX, are derivatives from the GD ASCOD series. I'm not sure how many degrees of separation there are between these cousins, but it shows that GD has some expertise in the field of tracked vehicles at this class level.

Personally I think we need to stay with and foster the growth of GD as a permanent supplier of CA kit because it has the only domestic plant capable of manufacturing at the scale we need.

IMHO, we need two fleets, a heavy tracked armoured fleet, and a medium wheeled fleet (and yes, yes, I know, the LAV 6.0 is bordering on heavy). I think that our medium wheeled fleet, assuming its all, on the road again, is large enough at roughly two mech brigades. I think we need an equal number of tracked IFVs and their support vehicles to equip three armour brigades (one prepositioned in Latvia and two at home for training and sustainment). It's the building of that fleet that could keep GD here occupied for a decade easily.

I question whether we would ever commit to such a plan at any scale. Although we may need to support GDLS London more on our own in the future and that may drive purchase decisions. Will a new government make up with the Saudis?

The ASCOD/AJAX/BOOKER seem to be about 10 tonnes heavier than the LAV series although the Boxer is very plump. And while our LAV 6 is 450hp the 700/Piranha/Boxer are 711/600/720 and the ASCOD/AJAX/BOOKER are 720/800/1000

Neither of which is GD product. The aim is to get a product that will keep our one main ground systems manufacturer online for decades to come. All systems have a Day One before they are "proven."

The M10 Booker is a GD product. If we really wanted, we could try to get that or a variant built in London.

As well, there's the return of investment in sinking R&D to design an all new IFV versus buying one that already exists, especially for a niche order that would likely.only be used by us.

Not to pooh, pooh the M10, but it's one of the last things I'd buy well after a long list of other capabilities are satisfied.

 

[quadrapiper]

Is the "two fleet" concept only inclusive of armoured (to one degree or another) vehicles?

Thinking of the various ATV- and Jeep/pickup-like, lightweight recce, etc. vehicles, and all things Arctic.

It's that a tracked assembly weighs more than a wheeled assembly for the same sized vehicle and that the amount of armour needed for an IFV application is thicker and heavier than one for a medium application APC. That additional weight leads to the need for a heavier-duty engine.

I question that? A wheeled assembly on say an 8x8 needs four differentials, 8 CV axles and more complicated suspension/steering. It also needs driveshafts between the axles. The whole underside of the vehicle ends up being taken up by the driveline. This in turn requires the vehicle to be larger for the same internal volume.

Tracks are heavy if made of steel which most military vehicles are. However a tracked vehicle needs only one drive axle and one differential As they drive from one end only. The differential is usually attached to the transmission so the power pack is quite a compact unit. the bogey suspension is simple and realativly light. This allows much of the belly of the vehicle to be used for other things like driver compartment or ammo storage. Allowing the vehicle to have a lower profile.

I think heavier vehicles use tracks for lower ground pressure and we think backwards thinking the tracks make the vehicle heavier.

So in short if you were to design a vehicle with a specified internal volume and a specified armour thickness in two versions, one tracked and one wheeled I believe the tracked version would be smaller and thus lighter.

I am not an engineer so I could very well be wrong.
