The Green Mace prototype was for many years on display at the IWM site at Duxford, but unfortunately was reclaimed by the Artillery Museum at the Woolwich Rotunda a few years before that closed. Hence the project that the Gunners apparently handed over to the RAF is out of sight in a reserve collection at least until the Gunners get a new museum.

I saw this exact green mace last week, the RA museum is currently awaiting funding to build a new building, all of the equipment and vehicles are locked away in a couple of warehouses. I walked in and the first thing I saw was this huge cannon that looked like a transformer. The RA museum have kept it in great condition and hopefully it will be back on display soon.

Love your work. You would have loved to meet my Dad. Joined Chilwell as an apprentice in 1930, Workshop Foreman in 1940, worked on every A series in the war and then on to Germany in the 40s and 60s, MoD, Chobham, Woolwich by then Technical Officer and so on. Centurion, Chieftain and a his views on some of them was "interesting". The muddle of the war years. He ended as head of Scales Branch in the 70s. He was told off by one General for doing wading experiments in Chieftain at 60 years of age. He did it because no one else could be found who would do it. A bit of a vandal was Dad and a very good advert for meritocracy. He rose from nothing and even at 80 plus to watch him work on a car engine was something. His favo tank was the scorpion. Claim to fame. He was nearly arrested for being drunk in charge of a DUKW on the river seven, along with some senior REME officers. I love to watch your videos, simply because I get to see what he worked on thanks.

Excellent work, well done. Just FYI, I joined the Guns Department at RARDE in ‘82. Stories about Green Mace still circulated as a couple of the guys were old enough to have been in the design branch at the end of the design, and there were always annoyed comments about how Bloodhound had finished it off. But I also distinctly remember being told that Green Mace was the small version of something they were thinking about that would use the same basic reload concept but be much bigger calibre. Knowing the guys involved, wouldn’t be at all surprised as a last ditch “let’s beat missiles at any cost” option.

Guns are likely to make a come back because of guided rounds. The Italians (Otto Malera) have been using a guided 76.2mm shell called DART since 15 years. It's beam riding. The Germans and Italians together built Vulcano 155mm GPS APDS with a 70km range and a Naval 5 inch version with a range of 80km. The Italians even ported it to their 76.2mm gun so now can hit a target 40km away with a 76.2mm gun. The proximity fuse can be replaced by a laser seeker or an infrared seeker (for naval targets). The US has a guided 57mm shell called MAD FIRES with its own seeker. So a 100mm gun might be quite effective, especially if a duel feed weapon able to choose between guided and conventional air burst (to deal with drones)

The 5.25 inch turreted twin gun was used on HMS Vanguard which was launched in 1946. Some sixteen in total. They also tried the rockets on warships but they did not last very long there either. I think the feeling was that it was bad enough that the enemy was trying to sink you without it being self inflicted.

The big problem for the V1 was that with Europe in allied hands the flight paths were highly restricted and the allies could concentrate their defenses. The other problems was that when launched the missile had a speed of 420mph at sea level (thios was beyond even the Tempest with 150 octane fuel) this deteriorated to about 360-370 in most due to the valves deteriorating. Nevertheless there were version with speed of as high as 515mph expected and reliable engines as wells as a turbojet version with double the range and a guidance system called Ewald-II. Willy Messerschmitt and Rober Lusser designed the Me 109. Lusser moved to Fieseler and designed the Fi 103. Messerschmitt loved his ex designers creations and wrote dozens of pages analyzing and proving how a production rate of 100,000 was possible.

Speaking of large caliber AA prototypes . . . The 1944/45 era 15cm gerat 56(?) was a German 150mm bore AA cannon with a two chambered autoloader. It was part of a late war project given to a few armaments manufacturers (G55,56, etc), resulting in some prodigal prototypes, but no series production. FlaK towers were armed with single or dual 12.8cm sFlaK40, plus a ring of small bore (2cm/3.7cm) autocannon.

The 12.8cm FLAK 39 and 40 were the most powerful AAA guns to see service in WW2 by anyone (everything else was experimental). The Germans did have a Proximity Fuse in development but they suspended work in 1940 to concentrate resources on the Battle of France and didn't get it restarted till 1942/43. By then its was too late to fire anything but experimental rounds but it would have been deadly. It used a cold cathode valve and electrostatic detection. It's code name was kuhglochen (little cow bell). Completely unjamable. Britain actually also succeeded in test firing proximity fuses in 1942. In the British fuse the shell was tracked using a corner reflector and when the echo from the shell and target merged a coded double pulse detonated the shell. By then the US fuse was nearing mass production. -Guns like the 150mm were banned by the Germans due to the excessive resources required. The Standard 8,8cm FLAK 37 had a muzzle velocity of 800 meters second and was not very effective above 20,000ft (reasonable to 25,000ft but engagement time at 30,000ft was about 11 seconds). The replacement was the 8.8cm FLAK 41 with a muzzle velocity of 1000m/sec. It had all sorts of issues such as blockages caused by changing from brass to steal cartirdges, vibraion at the high firing rates demanded. It worked in small numbers and the problems were solved by the end of 1944 (too late)

Is this the amazing AA gun with rotary magazines at Duxford. I remember looking at this with both military engineering and production engineering and thinking as a system it was probably doomed to failure. Reason being the rotary magazines. The likelihood of mis syncopation with such masses trying to engage high rates of fire is large and one in twelve rounds failure sounds quite good. For the systems of monitoring and adjustment available at that time I suggest it was beyond the bar. I think a straight feed system would have been better as long as the feed line was kept short because of the round plus case weight. I would not expect an industrial machine to perform well in such a capacity with a a rotating motion and the technology of the day and have experience of maintaining pre war machines up to a few years ago.

The 5.25in dual-purpose guns were originally designed for the Dido class Anti Aircraft Cruisers in about 1935 which are technically light Cruisers (6in and below = light Cruisers, 8in = heavy cruisers, as a rule of thumb in RN service) I believe by 1943, three RN turrets and guns were acquired by Anti-Aircraft Command and located in various positions around London, the one in the picture, I think, is the one located at Primrose Hill.
