While doing a search for M24's used by Chile,I came across these pictures.

It is post #77. This version has the 60 mm HVMS on it. It looks like they converted the Norwegian NM-116.

Doubtful.  Using the 60mm however makes sense as it provides commonality with the Sherman M51s which they bought from Israel with the 60mm in them.  I think they are just plain old M24s the Chileans have had for a long time.

Since the ROC did convert surplus M42 SPAAG into light tanks by replacing the stock turret with one from the M18 tank destroyer, can the same be done to the M19 SPAAG since both types use essentially the same stock turret?

Same turret ring so it should be possible with minimal modification.  The M18 is a pretty light weight turret so weight distribution shouldn't be too big a problem.  Give the M18's gun some improved ammunition and it would be quite handy as a tank destroyer in soft ground.

Just a thought, could a British 77mm HV gun, as used by the Comet, have been practically fitted to the M-24 turret?

My thinking was the 76mm in the M-10 was replaced with a 17pdr for the Achilles, the Wolverine also used the 76mm, so theoretically it could possibly take a 17pdr, earlier in this discussion fitting a Wolverine turret to an M-24 was considered doable.  Following this logic an M-24 with a Wolverine turret could conceivably be fitted with a 17pdr, it the vehicle could handle that could its standard turret be modified to take a 77mm?

Why?  Well the M-24 could have been retained / adopted as a light tank by Britain, Australia etc. post war and updated to use the same gun as another type in service, the Comet to not only upgrade combat power to give it a shot against T-34s encountered in Korea and also to streamline logistics.

Imagining upgraded RAAC regular and reserve M-24s serving with cavalry regiments along side M-113 in the 50s, 60s and 70s, including Vietnam.

Thanks, I imagine the 76mm or 17pdr would be too much for the standard turret but that the 77mmHV maybe do the job.  Already planning to buy the Bronco turned aluminium barrel for my Trumpeter E-10 when I saw a pick of the Norwegian M-24 and started thinking of this mix and whether it would be workable or too much for the turret.  I suspect it may be an issue as if I recall correctly the 75mm used in the base vehicle was actually a lighter version originally developed for the B-25G, suggesting that the standard 75mm was considered too big/heavy etc.  If the Cromwell was too small / light for a 77mm the smaller lighter M-24 could well be too.

If the US 76mm would be too much for the Chaffee turret, then the 77mm gun from the Comet should be, as well. I believe the 77mm was the more powerful of the two, so the length of the round and the level recoil would likely be greater, as well.

The 25 pdr may work, and the 95mm howitzer almost certainly would, too. Now, if you modified the Chaffee turret Firefly-style, then the British 77mm may work, but I won't be volunteering to load. You may have to go down to a 2-man turret Valentine/AEC-style, but British recon units weren't unused to that compromise, so I don't see that being a deal-breaker.

The Chaffee's M6 75mm gun was indeed a variant of the lightweight gun developed for the B-25G/H. As I understand it, they used the same round as the M2/M3, so the recoil forces should be similar, but the actual weight and bulk of the gun was considerably less. Now, obviously, I'm sure you could substitute a 6 pdr for the 75mm if you had a couple of competent fitters and a lazy afternoon.

The most powerful gun (recoil-wise) that I recall having been mounted in a Chaffee turret was probably the Israeli 60mm HVMS on the Chilean Chaffees.

Its what I was sort of thinking, you could do it on an M-41 but why as the 76mm is comparable, just a stretch too far for the Chaffee. 

Shame actually as it would have looked good and fitted my Antipodean Armour Fest ORBAT quite well.  Cavalry regiments and squadrons using upgraded M-24s supporting the Centurion/Conqueror/Chieftain tank brigade and the Comet/Leopard reserve brigades, as well as equipping the Recce Troop/Platoon of the Armoured Infantry Btn support companies until replaced by a more modern vehicle in the 80s.

I suppose a "re" (as opposed to "up")-gunning exercise could be for purely logistical reasons and opt for the 76mm L5A1 from the Saladin or even the L23A1 from the Scorpion in the 60s or 70s.

Looks like you'd only fit six troops in the rear section without an extension, maybe of it drops to a single engine or a pair of inline sixes more room could be found.

It is supposedly the "Orgeneral Tural Kariyeri" (Major General Tural [armored personnel] carrier) and was based on the converted chassis of M24 Chaffee light tank, which were transferred from US in numbers in early 1960's, after Turkey joined NATO.  It was designed as a reconnaissance and light troop transport vehicle.

Technical specifications of the Tural APC are as follows:

Crew: 12
Weight: 18t
Weapons: 1 x 57mm gun, 2 x 7.62 machine guns
Range: 100 miles
Speed: 58 km/h

A small number of vehicles were converted in mid 1960's and all retired in 1971.

How about an M24 armed with a 57mm/6 pounder instead of the 75mm?  While it might not be practical for fighting tanks larger than the M24 it might make an excellent infantry fire support vehicle where larger caliber 75mm high explosive could pose a possible danger to the supported troops.  Another benefit to the smaller caliber weapon would be an increase in ammunition carried on board the vehicle.  The subtle change in gun tube size would certainly catch some folks off guard :)

From what I understand, initially a 57mm weapon was considered.

It is post #77. This version has the 60 mm HVMS on it. It looks like they converted the Norwegian NM-116.


Interestingly, both the NM116 (with 90mm low pressure gun using HEAT rounds) and the Chilean upgrade using the IMI-OTO 60 mm Hyper Velocity Medium Support (HVMS) gun with APFs-DS-DT rounds offer much the same penetration performance (in excess of double what the original 75mm gun provided).

Idea related to Logan Hartke's Geriatric Army topic- M24 upgraded with Cockerill Mk.3 gun.  Sorta partially meant as a market successor to the DEFA F1 gun used on, amongst others, the NM116, the Cockerill Mk.3 not only has a wider variety of ammunitions but also will eventually have an ATGM designed for it.

Granted, in 2010 one would likely need a crystal ball to see that last one coming......

How about the French reassembly shop at Dien Bien Phu??



In order to improve the offensive capabilities of the units stationed here, an escadron of M24 Chaffee tanks from the 1st Cavalry Regiment (1er Régiment de Chasseurs á Cheval) was transferred here as well. Transporting them to the base however proved to be quite an undertaking and a serious issue. Dien Bien Phu was located 350km from Hanoi and could be supplied only by air. The French Air Force was operating the C-47 Skytrain and C-119 Packet, piloted by American volunteers – both relatively small aircraft, capable of transporting trucks, 105mm howitzers and men, but the 18 ton Chaffee was too heavy for them to carry. That’s why it was necessery to actually dismantle the tanks and transport them in pieces.

The tanks, transferred to Dien Bien Phu, were dismantled at the Gia Lam base in Hanoi by the men of the 2nd Armor Repair Company of the Foreign Legion (2e Compagnie de Reparations d’Engines Blindés Legion Etrangére), who managed to separate them into 180 pieces. In order to transport the largest pieces, the French had to borrow Bristol 170 Freighter planes from Air Vietnam – these were the largest planes, capable of landing at Dien Bien Phu. In the end however, it turned out that even so, the hull of the Chaffee was 150kg heavier than what the Freighter could carry – in order to actually fly over the mountains in the Tonkin region, the plane was stripped of all the unnecessary parts. They made it, but just barely. The operation to transfer the tanks was called Rondelle II and begun on 16.12.1953. In order to get the tanks going as fast as possible, the men of the 2nd ARCFL (reinforced by specialists from 1er Battalion de Réparations du Materiél from Saigon) did set up their shop straight at the Dien Bien Phu air strip. Two days later, first two tanks landed – albeit disassembled – on the Dien Bien Phu strip and their assembly was initiated immediately. Transporting the tanks took until the end of December 1953, for each tank, 2 Freighter trips and 6 C-47 trips were needed.
