T-34 Medium Tank

The T-34 Medium Tank is by far the most famous Soviet weapon of the Second World War, and has become a symbol of the Red Army’s desperate struggle against the Germans
The various versions of the T-34 have been known by at least three different designation systems in English language publications
The T-34-85 Medium Tank was the main Soviet tank in the last year of the Second World War, and was the only significantly improved version of the basic T-34 to enter production during the war.
The T-34 Medium Tank was built at seven different factories during the Second World War, starting with Factory 183 at Kharkov and the Stalingrad Tractor Factory, both of which would fall to the Germans during the war
The OT-34 was the designation given to over 1,500 T-34 Medium Tanks armed with a flamethrower in the hull.

SU-100 assault gun, SU-85 and SU-100 tank destroyers

The SU-122 was a self-propelled 122mm gun produced on the chassis of the T-34 Medium Tank, and was similar in concept to the early versions of the German StuG, designed to provide close support for the infantry
The SU-85 was a Soviet tank destroyer based on the SU-122 assault gun, which was itself built on the chassis of the T-34 Medium Tank.
The SU-100 was a Soviet tank destroyer developed as an up-gunned version of the SU-85 after the 85mm gun used in that vehicle was installed in the T-34-85.

Nos.28, 29, 30, 31, 32, 33, 34 and 34 Squadrons, RAF

No.28 Squadron spent the entire Second World War operating from India or Burma, at first as an army co-operation squadron equipped with the Audax and Lysander, then as a tactical reconnaissance squadron, equipped with the Hawker Hurricane.
No.29 Squadron spent most of the Second World War operating as a night fighter squadron, taking part in some of the earliest experiments with airborne radar before converting to the Beaufighter and then the Mosquito.
No.30 Squadron began the Second World War as a Blenheim bomber squadron based in Egypt, but went on serve as a fighter squadron in Egypt, Greece, on Crete and in the Far East, ending the war operating with Thunderbolt fighter bombers over Burma.
No. 31 Squadron spent the entire Second World War operating as a transport squadron, based in India.
No. 32 Squadron was one of the most successful Hurricane squadrons of the Battle of Britain, and was credited with 102 victories in the first half of the battle. It then moved to the Mediterranean, taking part in Operation Torch, the invasion of Italy and the liberation of Greece.
No.33 Squadron began the Second World War operating the Gloster Gladiator in the Western Desert, fought in Greece and on Crete, then fought against Rommel during the see-saw battles that ended with the victory at El Alamein, before returning to Britain to take part in the D-Day landings and the campaign in Western Europe.
No. 34 Squadron went through two incarnations during the Second World War, first as a Blenheim squadron based in Singapore, before reforming in India after the Japanese entry into the war. The squadron ended the war as a fighter bomber squadron, operating over Burma

PPSh-41 Submachine Gun

The Soviet PPSh-41 was the best mass produced submachine gun of the Second World War, and was produced in vast numbers during the war.

OT-26, OT-130, OT-133 and OT-134 flamethrower tanks

The OT-26 was the first of a series of flamethrower tanks based on the T-26 light tank.
The OT-130 was a second flamethrower tank based on the T-26 light tank, this time using the single turreted T-26 Model 1933
The OT-133 was the third of a series of flame thrower tanks based on the T-26 light tank, and was built around the improved T-26S
The OT-134 was the fourth and final entry in a series of flame throwers based on the T-26 light tank, and was the first to carry any other armament

T-26 Light Tank (Russia)

The T-26 Light Tank was produced in greater numbers than any other pre-war Soviet Tank, and was the most numerous tank in Red Army service in June 1941.
The T-46 Light Tank was developed in an attempt to improve the mobility of the T-26, the most numerous Soviet tank from the mid 1930s until the German invasion of 1941.
The T-25 Light Tank was a second attempt to improve the mobility of the T-26 light tank by installing Christie suspension

Panther Medium Tank

The Panzer V or Panther medium tank was developed at high speed to counter the Soviet T-34, and after a unsuccessful introduction to combat at Kursk developed into the best German tank of the Second World War.
The Panther I Ausf D was the first production version of the Panther medium tank, and was rushed into combat only a year after the design was first approved.
The Panther I Ausf A was the second production version of the Panther medium tank, and was very similar to late production Ausf Ds.
The Panther I Ausf G was the final version of the Panther to enter production during the Second World War, and was produced in larger numbers than the previous two versions combined.
The Panther I Ausf F was the final version of the Panther medium tank to be developed, featured a new type of turret, and was on the verge of entering production at the end of the Second World War
The Panzerbefehlswagen Panther Sd Kfz 267 was a very successful command tank based on the standard Panther I
The Panzerbefehlswagen Panther Sd Kfz 268 “Flivo” was the less common of the two types of command tank based on the Panther, and was designed to operate as an air to ground liaison officer
The Panzerbeobachtungswagen Panther was an artillery fire direction vehicle based on the Panther and designed to operate with the armoured artillery
The Panther II was developed during 1943 as a potential replacement for the Panther I, but never progressed beyond the prototype stage.
The Jagdpanther was the most powerful of a series of tank destroyers produced in Germany during the Second World War, carrying the same gun as the Jagdtiger, but on a vehicle 24 tons lighter, 91cm/ 3 feet shorter and 8km/hr fasterThe Bergepanther or Panzer-Bergegerät (Panther I) was a tank recovery vehicle based on the Panther medium tank, and produced to solve a problem caused by the ever-increasing weight of German tanks. The Panther Ostwallturm was a fixed fortification based around the turret from the Panther medium tank.

Douglas Havoc RAF Night Fighter

The Douglas Havoc was an impromptu conversion of lower powered French DB-7s, which achieved a certain amount of success as a night fighter and intruder in 1941 and 1942.
The Douglas Havoc I (Pandora) was a particularly unusual weapon which demonstrated the urgent need for any weapon capable of dealing with the threat from German night bombers during the Blitz.
The Douglas Havoc I (Night Fighter) was one of a series attempts to make use of the relatively large number of French DB-7s which arrived in Britain after the collapse of France in June 1940
The Douglas Havoc I (Intruder) was designed to operate as a night time intruder over occupied Europe, and was produced by modifying late production French DB-7s
The Douglas Havoc II (Night Fighter) was produced by installed a new solid nose carrying twelve guns to 100 French DB-7As which reached Britain after the collapse of France

Douglas Boston (RAF)

The Douglas Boston was the best of a series of American light bombers to serve with the RAF during the Second World War, serving with ten RAF and SAAF bomber squadrons and three night intruder squadrons.
The Douglas Boston I was the designation given to 20 Douglas DB-7 bombers originally ordered by France, but that entered service with the RAF
The Douglas Boston II was the British designation for late production French DB-7s, powered by the Pratt & Whitney R-1830-S3C4-G Twin Wasp with a two-speed supercharger.
The Douglas Boston III was the most important version of that aircraft in RAF service, with a total of 768-771 aircraft produced. It was also the first British version to be actually be used as a bomber, and the first version to have come from the original British order for the Douglas DB-7B
The Douglas Boston IV was the British version of the glass-nosed A-20J Havoc.
The Douglas Boston V was the RAF designation for the glass-nosed A-20K Havoc, and was the final version of the aircraft to see service with the RAF

Douglas A-20 Havoc

Very few aircraft attracted a wider range of designations than the Douglas DB-7/ A-20 Havoc/ P-70 Nighthawk/ Havoc night fighter/ Boston bomber
The Douglas A-20 Havoc may not be one of the best known bombers of the Second World War, but it was used by seven Bombardment Groups, fought in the south west Pacific, took part in the invasions of North Africa, Italy, France and Germany, and remained in service until the end of the war
The Douglas A-20 was the first version of the Havoc to be ordered by the US Army Air Corps.
The Douglas A-20A was similar to the original A-20, but without the turbo-superchargers used on the earlier version of the Havoc
The Douglas A-20B was the first version of the Havoc to be produced in large numbers for the USAAF, but it lacked self-sealing fuel tanks and did not have enough armour.
The Douglas A-20C was originally produced for export to Britain and the Soviet Union under lend-lease, but a large number were retained in the United States after Pearl Harbor
The Douglas A-20D was the designation given to a lightened version of the Havoc that would have been powered by turbo-supercharged R-2600-7 engines.
The Douglas A-20E designation was given to a small number of Havocs used for experiments with lightened fuselages
The Douglas A-20F was the designation given to a version of the Havoc armed with a large 37mm gun in the nose, built on a modified A-20A chassis
The Douglas A-20G saw the biggest change to the design of the Havoc with the replacement of the glass bombardier’s nose by a solid nose carrying six forward firing guns.
The Douglas A-20H was a minor variation on the A-20G, the first solid-nosed version of the Havoc.
The Douglas A-20J saw the reintroduction of the glass bombardier’s nose, replaced on the A-20G by a solid gun nose
The Douglas A-20K was a glass-nosed “lead ship” produced to work alongside the solid nosed A-20H
At the start of the Second World War the US Army Air Corps lacked a modern radar equipped night fighter, and so it was decided to copy the RAF and convert a number of Douglas A-20s into P-70 Nighthawks night fighters.
The Douglas BD was the US Navy designation for nine A-20 Havocs, used as high speed target tugs
Forty nine Douglas A-20 Havocs were converted to act as photo-reconnaissance aircraft, under the designation Douglas F-3

Douglas DB-7 (France)

The Douglas DB-7 was one of a number of American aircraft ordered in large numbers by France during 1939 in a vain attempt to reequip the Armèe de l’Air before the outbreak of war with Germany

Martin Maryland and Baltimore light bombers

The Martin 167 A-3 was a light bomber designed for a US Army bomber contest of 1937-38, but that entered combat with the French Armée de l’Air, before becoming the basis of the RAF’s Maryland and Baltimore bombers.
The Martin Maryland was a light bomber originally developed to satisfy a US army specification and which entered British service after the fall of France.
The Martin Baltimore was a light bomber developed by the Glenn L. Martin Company from its Model 167 Maryland to satisfy a British specification.
We provide a list of squadrons that used the Martin Baltimore light bomber
The Martin Baltimore I was a light bomber developed from the earlier Maryland by increasing the width and depth of the fuselage and installing more powerful engines and more guns.
The Martin Baltimore II differed from the Mk I only in that it was delivered with two 0.30in Browning machine guns in the rear dorsal position in place of the single gun of the Mk. I
The biggest problem with the earlier versions of the Martin Baltimore had been the poor rear guns – two hand operated Vickers “K” guns which proved to be difficult to use in combat – and so the Baltimore III was equipped with a powered gun turret
The Martin Baltimore IIIA was the first version of the aircraft to be provided under lend-lease, and was armed with a different turret to the Baltimore III.
The Baltimore IV was very similar to the Baltimore IIIA, differing only in some internal equipment.
The Baltimore V was the final version of the aircraft to be produced, and differed from the earlier versions in using more powerful Wright R-2600-29 Cyclone engines.

Consolidated PBY Catalina

The Consolidated PBY Catalina was the main long range reconnaissance aircraft in use with the US Navy in the first half of the Second World War
The Consolidated PBY Catalina was the main long range reconnaissance aircraft in use with the US Navy in the first half of the Second World War. We now add articles on the development of the PBY Catalina, the combat career of the Consolidated PBY Catalina with the US Navy and with the RAF, and lists of US Navy PBY Squadrons and RAF Catalina Squadrons that used the aircraft.
Canada developed a very sizable aircraft industry during the Second World War, and one of the aircraft it produced in large numbers was the Consolidated Catalina.
The Consolidated PBY-1 was the first production version of the Consolidated Catalina, which would be produced in far larger numbers than any other flying boat
The Consolidated PBY-2 was the second production version of the Catalina flying boat, and was very similar to the PBY-1, the main differences being on the tail.
The Consolidated PBY-3 differed from the previous version of the Catalina in having more powerful 900hp R-1830-66 Twin Wasp engines in place of the 850hp engines used on the PBY-2.
The Consolidated PBY-4 was the last of the early versions of the Catalina fly boat, each of which was ordered in small numbers in the period before the Second World War.
The Consolidated PBY-5 was the first version of the Catalina to be produced in large numbers, and the last to be a pure flying boat, and yet at the start of 1939 it had looked as if the PBY-4 was to be the final production version of the aircraft.
The Consolidated PBY-5A was the first version of the Catalina to be equipped with wheeled landing gear, turning it from a pure flying boat into an amphibian, capable of operating from sea and land bases.
The Consolidated PBY-6A was the last production version of the Catalina amphibian, and combined the features introduced during the production run of the PBY-5A with the new tail designed for the PBN-1 Nomad
The Consolidated OA-10 was the USAAF’s designation for the Catalina flying boat, used by the air force for air-sea rescue duties in the vast expanses of the Pacific.
The Naval Aircraft Factory PBN-1 Nomad was an improved version of the Consolidated Catalina, produced by the same facility that had produced the design for the XPY-1, the first flying boat to be produced by Consolidated and a direct ancestor of the Catalina.
