The Chieftain’s Hatch: Bigger Turret, Less Room

hatchlogoOver at the World of Tanks website, tank researcher Nicholas “The Chieftain” Moran has posted an article on Sherman tank turrets and guns.  Specifically, he found some archival materials about an attempt to put a 75mm gun into the T23 turret (this is basically the same turret as the 76mm armed Sherman tanks).  Oddly enough, they found that the 75mm gun did not fit.  While this may seem counter-intuitive since the T23 turret was larger than the 75mm gun turret, the answer lies in the shape of the turret and the placement of the trunnions.  The Chieftain uses this example to make the larger point that up gunning a tank turret is more than just a simple case of  making sure the turret ring is big enough and jamming in a new gun.

Excerpt:

One of the problems with Firefly was that the turret was a little cramped.

The 17pr is not a small gun to cram into a turret bustle measured in inches. US Army Ordnance had a crack at putting the somewhat smaller and lighter 76mm into the same turret, and Armored Force found it unsatisfactorily cramped and rejected it.

Another lesser-known issue for Firefly is that in order to be converted, the tank had to be the 75mm one with the smaller turret. This is partly why the 75mm Sherman remained on the production lines even after the US Army decided to switch to the 76mm. But it raises the question: why did they mandate use of the 75mm tank? Surely the 76mm turret, bigger as it was, would have been a better match, and reduce the limitations the Firefly was under. How could the British miss this?

The Chieftain’s Hatch: A Bigger Kitty

Over at the WoT forum, Nicholas “The Chieftain” Moran has posted a new article about the development of the Tiger II tank.  Excerpt below, read the full article here.

hatchlogo (1)VK 45.03. Tiger III. Tiger II. Tiger Ausf B. And they’re all the same tank. Even after reading and re-reading the books on King Tiger’s development (Notably the Jentz/Doyle one), I’m still a little confused, though perhaps a little less than some. You’d think that a country with a reputation of organization such as Germany would have had a system which was easier to decipher, but as Hilary Doyle intimated in Operation Think Tank, the various companies all competing for contracts tended to be as much interested in the money as they were their patriotic duty to see the war won. Doubtless the winds of fortune changed as the company leadership leaned upon their patrons in the political hierarchy which had no small role in the development of vehicles by the middle of the war. Anyway, since the VK 45.03 premium tank is now on sale, let’s have a look at the background.

The Chieftain’s Hatch: Marines via Australia

hatchlogoOver at the World of Tanks website, Nicholas “The Chieftain” Moran has posted an article written by historian Ken Estes about the career and experiences of WW2 era Marine tanker Lt. Col. Rowland Hall.

Excerpt:

Anzac Day is a day of solemn commemoration in Australia and New Zealand. The last time I touched upon this was two years ago, with a bit of background, and then an overview of one of the feats of arms of the Australian forces: The Defense of Tobruk.

Those of you who have seen the miniseries The Pacific might remember an episode set in Melbourne. Australia’s role wasn’t just to send manpower and equipment to fight for the Crown. The country had a similar role in the South Pacific as the UK did in Europe: A bulwark to hold on the edge of the theater, a staging and training area for future operations, and a place for some R&R.

Some time ago, Ken Estes sent me an article for the Hatch: the reminiscings of Marine officer Rollo Hall. Rollo’s writings do not focus on Australia per se — they are his view of the war as a whole and of the development of the Marine Corps tank force, but the amount of words he wrote about his time in Australia is indicative of just how important the country was to the prosecution of the war for the US, both in practical terms for combat training, as well as the morale effect of cameraderie with allies. This should give something of a holistic view of the general environment. So, I hand the keyboard over to the late Rowland Hall.
