British Helicopters History
Published 17 Jan 2020Major rationalisation of the UK aircraft industry occurred during the 1960s. With the acquisition of Bristol Helicopters, Fairey Aviation and Saunders-Roe, Westland Helicopters transformed itself into Britain’s only helicopter maker with plants at Yeovil, Weston-super-Mare, Eastleigh, and Hayes, producing helicopters for all roles.

T-55: 70 Years Old. Still in Service
The Tank Museum
Published 22 Aug 2025No tank in history has been produced in the quantities that the T-55 and its relatives have. Some sources suggest as many as 100,000 have been built since 1946, this tank is still seeing service across the globe. So how come this 80-year-old tank is still in service in 2025?
When looking at its predecessor, the T-34, the move to the T-55 looks like a massive leap in design. But there is a clear evolutionary progression – there is just a missing link. The T-44 laid the groundwork for future Soviet tank design – pioneering torsion bar suspension and a transverse engine.
It was soon decided that the T-44 would require a new 100mm gun to replace the 85mm. This new model would be called the T-54. While NATO classes both the T-54 and 55 as the same vehicle, the T-55 is a substantially better tank. A comprehensive series of upgrades made this an effective force on the battlefield.The T-55 would prove popular with forces around the world. It would even go head-to-head against itself in the Iran-Iraq War of the 1980s. Eventually the T-55 would become outdated as NATO technology became more and more advanced. But it is still in service in the conflict in Ukraine – why?
The Russian army, despite the stereotype of having unending stockpiles of weaponry, have been struggling to keep up with the astounding loss rate the Ukrainians have been able to inflict on them. This has resulted in older and older vehicles being dragged out of those large storage depots across Russia, mainly being used as mobile, protected artillery.
The T-55 has endured partly due to its sheer numbers, availability and upgradability. Its performance on the battlefield has varied, but its basic but effective design has proven itself again and again throughout the decades. It is worth reiterating how remarkable it that a vehicle conceived at the end of the Second World War is still even a consideration for armies 80 years on.
In this video, historian James Donaldson explores the history of the most-produced tank in history – the T-55. This Soviet design has its roots in the iconic T-34, evolving through the years to become an effective fighting machine that was sold around the world. Despite manufacturing ending in the 1980s, this tank is still a feature on the battlefield, with both sides making use of T-55s in the current conflict in Ukraine. It may not be engaging in tank-on-tank combat as initially intended, but the T-55 is still providing a useful, effective and relatively cheap addition to the arsenal of many armies in the 21st Century.

KH-9: B&T Remakes the SITES Spectre Just Because It’s Cool
Forgotten Weapons
Published 9 Apr 2025Karl Brügger, CEO of B&T, is a true gun nerd and avid competitive shooter. When he got his hands on the Spectre SMG with its quad-stack magazine and weird DA/decocker fire control system, he thought it was really neat. So neat that he decided to buy the project from its Italian creators and put it back into production. But they had thrown out all the drawings and tooling when the gun wasn’t successful, and so Brügger had to recreate it from scratch on his own. Cue the Karl’s Hobby 9!
Without Spectre magazines to use, or the tooling to make them, B&T instead found a batch of quad-stack Suomi magazines and used those. They faithfully recreated the DA firing system and decocker, and decided to make a limited back of 222, because this was just a fun side project and not something that would be commercially popular. Except that they sold out really fast. And so another batch was done, this time using APC-9 magazines, since the supply of Suomi mags had been exhausted. Then when they found some Suomi drums, they did another limited batch for those. All of these sold out rapidly, and so the project grew legs. Next up, it became the KH-9 Covert, because what makes a gun cooler than adding folding bits to it?
It remains a limited-production item made in both Switzerland and in the US. Turns out that Karl Brügger isn’t the only guy who thinks they are really neat …

Six Reasons Operation Market Garden FAILED
The Tank Museum
Published 3 April 2025Operation Market Garden failed because the tanks of XXX Corps did not reach the Paras in Arnhem in time. Many historians have argued that the British armoured column “let the side down”. But is this actually true?
We reckon there are six reasons why the operation was a total disaster. It was a poor plan from the get-go, relying on a rate of advance that would outmatch the German invasion of France in 1940. Bad weather prevented the deployment of badly-needed reinforcements, and the terrain Guards Armoured were expected to traverse – a single road with impassable conditions on either side – significantly hampered the efforts of the tank crews.
Poor intelligence also meant that the British column was not prepared for resistance from a retreating and desperate German Army. It was a combination of all these factors that caused Market Garden to unravel completely.
Despite the complications, many acts of valour were carried out by both the airborne and armoured divisions, including the legendary assault across the Waal by the US 82nd Airborne.
So, join us as we explore these six reasons why Operation Market Garden failed and decide for yourself whether XXX Corps could have done anymore.

UK vz.59 Czech Universal Machine Gun: History and Mechanics
Forgotten Weapons
Published 21 Mar 2018In 1952, Czechoslovakia adopted a whole new family of small arms, including the vz.52 pistol, vz.52 rifle, and vz.52 light machine gun. The rifle and LMG were both chambered in the Czech 7.62x45mm cartridge, and both would be adapted to the Soviet standard 7.62x39mm a few years later, in 1957. Very shortly thereafter, the Czechs would also introduce a heavier universal machine gun version in 7.62x54mmR under the designation UK vz.59 (universal machine gun model 59).
The UK 59 was basically a scaled up sibling of the vz.52 and vz.52/57 machine guns, although it fed from a belt only, where its smaller predecessors had allowed either belt or magazine feed. It used a pivoting locking block system much like the Walther P38 and Beretta pistols, in conjunction with a long stroke gas piston much like that of the vz.26 light machine gun.
The weapon did not see much interest outside of Czechoslovakia, although it does remain in service in that region in the modernized 7.62x51mm iteration.
Thanks to Marstar for letting me examine and shoot their UK vz.59!

Confederate Morse Carbine: Centerfire Cartridges Ahead of Their Time
Forgotten Weapons
Published 23 Oct 2017George Morse of Baton Rouge patented a design for a remarkably modern centerfire cartridge and breechloading rifle action in 1856 and 1858, using a standard percussion cap as a primer. This was coupled with a gutta percha washer for sealing and a rolled brass cartridge body that was strong and robust — easily reloaded, if somewhat complex to manufacture.
After positive trials by the Army and Navy, Morse received a contract to make first complete guns and then a royalty contract for the conversion of existing muskets to his system. Work began at the Harper’s Ferry Arsenal, but money ran out with only 60 conversion completed. When the Civil War broke out, Morse chose to side with the Confederacy, and the tooling for his conversions was taken from the captured Armory to be put to use. He initially set up in Nashville, but the city fell to the Union in 1862, and he was forced to relocate to Atlanta and the Greenville South Carolina. It was in Greenville that Morse was finally able to manufacture guns in quantity, and he built approximately a thousand brass-framed single shot cartridge carbines for the South Carolina state militia.
Unfortunately for the Confederacy, the infrastructure to supply a modern type of cartridge ammunition really did not exist in the South, and this crippled any chance of Morse’s carbines becoming a significant factor in the war. The best technology in the world is still of no use if ammunition cannot be provided!
This Morse carbine is of the third type, using a sliding latch on the breechblock to hold the action closed when firing. Two previous versions used different and less secure systems, but this third type was introduced around serial number 350 and would comprise the remaining 2/3rds of the production run.

The First Poison Gas Attack of WW1: 2nd Battle of Ypres 1915
The Great War
Published 15 Aug 2025By April 1915, the Western Front was mired in trench warfare. Germany’s new Chief of Staff, General Erich von Falkenhayn, didn’t think his army could break the deadlock, and Germany needed to help struggling Austro-Hungarian forces in the East. Before the Germans turned against Russia though, they decided to attack in the West to keep the Allies off balance. They chose to strike at the vulnerable Ypres Salient – and they would support the coming offensive with a weapon their enemies had never seen.

Stocked FN Model 1903
Forgotten Weapons
Published 26 Aug 2015The FN Model 1903 was a Belgian-made scaled-up version of John Browning’s model 1903 pocket hammerless pistol. The pocket hammerless was made in .32 ACP and .380 calibers for (primarily) the civilian market in the US by Colt, and the FN model was chambered for the more powerful 9x20mm Browning Long cartridge, with military and police contracts in mind. The most common source of the FN pistols in the US is from the Swedish contract for the guns, but they were sold to a number of other nations as well.
This example is from the Russian contract, which included shoulder stocks with the pistols. Many military automatic pistols from this time were offered with the option of combination holster/stock units, which could be used to provide improved accuracy to the shooter. The stock for the FN 1903 is a bit different than most, in that it requires the use of an extended 10-round magazine instead of the standard flush-fit 7-rounder. As with most such original guns, these have been specifically exempted from NFA regulation in the US.

“Just war” theory and nuclear weapons practice
On Substack, Nigel Biggar discusses the postwar argument about whether the use of nuclear weapons against Japan was justified or not:

Atomic cloud over Hiroshima, taken from “Enola Gay” flying over Matsuyama, Shikoku, 6 August, 1945.

For pacifists, Christian or otherwise, the answer is clear: since any deliberate killing is wrong, the dropping of atomic bombs on Hiroshima and Nagasaki on 6 and 9 August 1945 was wrong about two hundred thousand times over.
But that clear answer generates further questions whose answers aren’t so obvious. If killing is always wrong, then the United States should never have gone to war against Imperial Japan and therefore its ally, Hitler’s Germany. What, then, would have stopped the triumph of brutally racist Japanese imperialism in Asia and massively murderous Nazism in Europe? The noble witness of innocent non-violence?
Unfortunately, the historical evidence is that the kind of people who ran the slave-labour camps in Burma, and the likes of Dachau in Germany and Auschwitz in Poland, were not at all shamed by the face of vulnerable innocence; on the contrary, it excited their lust for domination and they fed upon it.
On the other hand, those who think that war can sometimes be justified, might judge that the mass killing of civilians by the atomic bombs was, simply by its massive extent, indiscriminate and therefore unjust. But there are two problems here. The first is that the vast majority of people, certainly in the UK and the USA, regard the war against Hitler and his allies as morally justified, notwithstanding the fact that that cost between 60 and 80 million deaths, well over half of them civilian.
And the second problem is that the ethical tradition of “just war” thinking doesn’t say that we may not kill civilians, even on a massive scale; it only says that we may not kill them intentionally. If a military objective can’t be achieved except by risking the possible or probable deaths of civilians, then it may still be attempted, provided that the objective is sufficiently important, militarily, and that all reasonable measures are taken to avoid or minimise the side-effect of civilian casualties. The reason for this permissiveness is that in most circumstances just war would be impossible to prosecute otherwise.
So, for the “just war” proponent, if the intention in dropping the atomic bombs on Japan was to destroy vital military or military-related targets, and if there was no more discriminate way of achieving that end, then the bombing was morally justified. It was deeply, deeply tragic—but nevertheless just.

Negev 7: Israeli Scales up to a 7.62 NATO Machine Gun
Forgotten Weapons
Published 31 Mar 2025The Israeli Negev machine gun had a rather long development cycle, beginning in 1985 but not seeing final completion and issue until 1997. Once on the market, it proved to be a pretty successful weapon, used by the Israeli military and also a number of export client around the world. In 2012, IMI released an improved newer version, the Negev 7. This was made exclusively as a 7.62mm NATO caliber gun, as opposed to the original Negev which was only made in 5.56mm NATO.

Speed vs Armour: The Unexpected History of Fast Tanks
The Tank Museum
Published 21 Mar 2025Would you rather go to war in a tank that was quick but lightly armoured – or heavily armoured but slow?
The concept of fast tanks has existed since the First World War, but making a tank fast is easier said than done. You can increase the speed, but only by compromising the other two sides of The Iron Triangle.
Whilst a good power to weigh ratio is key to making a tank go fast, there are other factors that need to be considered. J Walter Christie pioneered the innovative helicoil spring suspension system – an invention that allowed tanks to cope with travelling at high speeds across country. Although not picked up by the US Army, the brilliance of Christie’s suspension was recognised by the Soviets and soon made an appearance on the BT-Series of tanks – and most effectively on the T-34.
Back in the UK, the newly mechanised cavalry was making use of some brand-new Cruiser tanks. Whilst these were fast vehicles, this was coming at the cost of effective protection. Some military thinkers advocated for the concept of “speed as armour” but results were mixed – with the Crusader and Cromwell both proving to be capable tanks.
After the war, the British Army finally moved on from “speed as armour” and settled on sacrificing a bit of speed for the sake of better protection. This was incorporated first into the concept of Universal Tanks and remains a fixture in the modern Main Battle Tank.
So, we’ll ask again. Would you rather go to war in a tank that was quick but lightly armoured – or heavily armoured but slow?

Erma EMP36: External Form Factor of the MP40
Forgotten Weapons
Published 26 Mar 2025The German military began looking for a new submachine gun design in secret in the mid 1930s. There is basically no surviving documentation, but the main contenders appear to have featured: Hugo Schmeisser’s MK-36,II and Erma’s EMP-36. Today we are taking a look at one of two known examples of the Erma design at the VHU in Prague. Designed by Heinrich Vollmer, this is a plain blowback open bolt system chambered for 9x19mm. It is massively more complicated than such a simple design has any right to be, though. Elements like the tiny set screw holding together the recoil spring assembly and the detachable bolt face are, frankly, nutty to include in a prospective military design.
However, Vollmer’s design had a number of external design features that were deemed very desirably by the German military. The pistol grip and very compact underfolding stock were both admirable, and the muzzle rest system was also of interest (in a simplified form). Ultimately, the result of testing of the Erma and Schmeisser prototypes was a combination of their features into a hybrid design. The Erma provided the external form factor, and the Schmeisser contributed the internal mechanics for the MP38 and in turn MP40.

Debunking the idea that Japan was about to surrender anyway
Dr. Robert Lyman on the common misunderstanding of Japan’s situation in July and August of 1945 — no, they weren’t “on the brink of surrender so atomic bombing was unjustified” … instead, they were intending to make the assault on the Home Islands the biggest bloodbath ever:

Atomic cloud over Hiroshima, taken from “Enola Gay” flying over Matsuyama, Shikoku, 6 August, 1945.

It’s the anniversary of Hiroshima again today. I wasn’t going to write anything to mark the event (more coming next week on VJ Day), but I’ve been triggered already by nonsense on the radio which suggests that the atomic bombs on Hiroshima and Nagasaki were unnecessary, because Japan was about to surrender.
Nonsense. There is not a shred of real evidence to support this idea. In fact, the evidence that Japan wanted to keep on fighting is irrefutable. And yet this lie persists, despite the deluge of scholarly work demonstrating Japan’s commitment to the ritual suicide of its entire nation right until the end, when Hirohito pulled the plug. If you are in any doubt about the facts of the case, as opposed to the propaganda, read Toland’s Rising Sun (1970), Frank’s Downfall (2001), Spector’s In The Ruins of Empire (2007), Pike’s Hirohito’s War and, more recently, Stewart Binn’s Japan’s War (2025). All are excellent, clear, analytical and well researched. There are lots more, too.
Why does this canard keep on popping up? Is it because people don’t read? Or is it that they just don’t want to believe in the necessity of such a dramatic event to force Japan to surrender and thus bring about an end to the greatest man-made tragedy the world has ever suffered? The origins of this wishful myth in fact derives from hard right nationalist propaganda in post-war Japan (driven by Admiral Suzuki himself), quickly lapped up by the gullible and wishful thinkers in the West. Its one of the most enduring of the Hiroshima and Nagasaki myths, in part because it seems palatable to many, and because it is inherently anti-American.
What is the real story? In short, the Allies tried hard to persuade Japan to surrender. They demonstrated unequivocally to Japan that it was going to lose the war by defeating its armies and by beginning the long, slow and painful crawl towards the Japanese home islands. All the books I’ve mentioned note the extreme chaos of Japanese decision-making before and during the war. Who really was in charge? Who could one talk to, to secure a commitment to negotiate? In any case, the chaotic government under Koiso which replaced that of General Tojo following the fall to the Americans of Saipan in 1944, made not a single effort to engage with the Allies to seek terms. This government also collapsed on 5 April 1945. The replacement prime minister was Admiral Suzuki, and it was from this man that the myth seems to have arisen, after the war, that Japan was considering surrender and that the A-bombs were unnecessary. This is not true. During his entire time as Prime Minister he resolutely refused to do anything but continue to fight, unless the ending of the war could be secured on Japan’s terms. There were some initiatives to persuade the Suzuki government to surrender, but none of them amounted to much, because they didn’t engage directly with the government in Tokyo, and they didn’t derive from the Allied powers. The evidence that peace-feelers were being put out by various sources (such as the Vatican) in 1944 and 1945 is evidence only that the Japanese government ignored them. None were taken seriously in Tokyo.
Indeed, throughout the period of the Suzuki government, the war parties were dominant. In early June the military Supreme Command submitted a paper entitled The Fundamental Policy to be Followed Henceforth in the Conduct of the War, in which it demanded that the government confirmed that Japan would fight to the very last Japanese in an act of national suicide leading to the “honourable death of the hundred million”:
With a faith born of eternal loyalty as our inspiration, we shall – thanks to the advantages of our terrain and the unity of our nation, prosecute the war to the bitter end in order to uphold our national essence, protect the Imperial land and achieve our goals of conquest.
The proposition was passed, not unanimously, but overwhelmingly nonetheless.
There were some in the government – interestingly including Tojo himself – who saw that this was self-defeating, and that Japan must negotiate to secure acceptable peace terms. Naively, it was hoped that this would enable it to retain parts of its empire. Suzuki was part of this group who thought that Japan could negotiate favourable terms to end the war, in the form of a negotiated settlement such as that had brought about the end of the Russo-Japanese war in 1905, but when he suggested this in parliament on 13 June he was shouted down by the war mongers. Hirohito then endorsed an approach to the Soviets in late June. Bizarrely – though Moscow was neutral in the Far Eastern war at this point – Tokyo’s emissaries suggested that the USSR and Japan join forces to rule the world. It was yet more evidence of how Tokyo fundamentally misunderstood the world, and its enemies, and the way the war would have to end: complete and utter surrender by Japan.
Moscow, of course, scorned these “negotiations” as meaningless.

Schmeisser MK-36,II – The Mechanics of the MP40
Forgotten Weapons
Published 24 Mar 2025The German military began looking for a new submachine gun design in secret in the mid 1930s. There is basically no surviving documentation, but the main contenders appear to have featured: Hugo Schmeisser’s MK-36,II and Erma’s EMP-36. Today we are taking a look at the two known examples of the Schmeisser design at the British Royal Armouries. It is a simple blowback design with a full wooden stock, and chambered for 9x19mm (although the second example, made for Hungarian trials, is in 9x25mm). It does have a quite strange magazine safety, which prevents the bolt from opening if a magazine is not present — the purpose of this is a mystery to me.
The Schmeisser gun was simple and effective mechanically (expect for that weird safety), and it ultimately contributed its magazine, bolt, and fire control system to the MP38 and MP40 design. In exchange, the Haenel company that Schmeisser works for was one of the two initial MP38 manufacturers.
Many thanks to the Royal Armouries for allowing me to film and disassemble this unique prototype! The NFC collection there — perhaps the best military small arms collection in Western Europe — is available by appointment to researchers: https://royalarmouries.org/research/n…

ZB37: Czechoslovakia’s Super-Heavy Machine Gun
Forgotten Weapons
Published 12 Mar 2025The ZB37 began in 1930 as a design by none other than classic Czech arms designer Vaclav Holek. The Czechoslovakian military was still using the Schwarzlose heavy MG, and wanted something to replace it. To fill all the roles intended, there would eventually be three different models of the ZB37 — one for infantry, one for fortresses, and one for vehicle mounting.
Note that the factory designation for this gun at Brno began as the ZB50, and iterated to the final version being the ZB50. However, it was identified by the military as the ZB37 (for 1937, the year of adoption).
After a series of redesigns, an early version of the gun is finally adopted in 1935 as the ZB35. A series of improvements leads to the final ZB37 model. About 500 of the early ZB35s were produced, and most of these were used to fill export sale contracts. By the time World War Two begins, the Czechoslovak military has about 5,000 of the guns in its possession.
Interestingly, the gun uses a hybrid recoil and gas operating system, with a tilting bolt. It has two rates of fire that can be chosen, and uses the rear spade grips as the charging handle. It is belt fed, using continuous 100- and 200-round metallic belts and chambered for the 8x57mm Mauser cartridge.
During the war, both German and British forces made substantial use of the ZB37. The Germans purchased ongoing production from Brno, and the British had actually purchased a production license before the war began. For the British, the gun was called the BESA and used in several armored vehicles (still in 8mm Mauser) — with about 57,000 being made during the war. A number of export sales were also made, including Romania, Persia, China, and several others. In 1946 another 3,000 were ordered and manufactured for fortress use in the Czech Republic, serving until the end of Communist control of the country.
Thanks to Sellier & Bellot for giving me access to this example to film for you!
