The Italian Obice da 305/17 G. Mod. 1917 Howitzer

This article is on the Italian Obice da 305/17 G. Mod. 1917 howitzer circa the First World War. I wanted to write this when I noted a number of pictures of this piece that were misidentified; and no details. After finding some good Italians sources I can now write something. Often described online as an Italian self propelled gun; nothing could be farther from the truth. This is the antiquated Italian Obice da 305/17 G. Mod. 1917 howitzer circa the First World War.

The Italian Obice da 305/17 G. Mod. 1917 howitzer circa the First World War.

Often described online as an Italian self propelled gun; nothing could be farther from the truth. This is the antiquated Italian Obice da 305/17 G. Mod. 1917 howitzer circa the First World War.

As can be seen from the photos below, the howitzer could be set in a fixed position or in the wheeled version which was a portion of the De Stefano (D.S.) carriage which compensated for it’s recoil from the use of inclined ramps. The tracks pictured on the wheels are likely for transport only when it isn’t on it’s rail assembly; they are pedrail wheels. Designed in 1908 and built between 1914 and 1917, a total of 44 were built by Armstrong-Pozzuoli and Vickers-Terni. This howitzer was 305 mm.

The Obice da 305/17 G. Mod. 1917 howitzer required a team of individuals and equipment to disassemble and move it; the below pictures illustrate the gun along with it disassembled for transport by tractors.

The M65 Atomic Cannon 280mm Towed Artillery

The M65 Atomic Cannon 280mm Towed Artillery.

The M65 Atomic Cannon 280mm Towed Artillery; circa 1952 and capable of firing a nuclear device, this artillery piece was nicknamed Atomic Annie.

Circa 1952, the US M65 Atomic Cannon, was a towed artillery piece capable of firing a nuclear device. It would be deployed starting in 1953 in Europe and Korea; and retired in 1963. In 1949 Robert Schwartz was tasked with the project intended to create a weapon to form a portion of the deterrent to the perceived threat of the Soviet Union at the time. Schwartz was sequestered under guard watch in a room for 15 days at the Pentagon while he designed what would become the M65. Not long after development began, the project was transferred to the Picatinny Arsenal; which was given the task of designing the payload for the M65. The initial design created by Schwartz used the German K5 railroad gun as a basis; the design was scaled to use a 240 mm shell which was the maximum size available to arsenal. Again Schwartz was sequestered to finalize the design including the method of transportation for the M65. The project was approved by the Pentagon after the intervention of Samuel Feltman, Chief of the Ballistics Section of the Ordnance Department’s Research and Development Division. After a three-year development process led by Feltman, the project was finished by 1952. Although Feltman led the team he did not see it to fruition, passing away in late 1951. The Technical Division Laboratory at the Picatinny Arsenal would be renamed the Samuel Feltman Laboratories. 20 M65 artillery pieces were made at a cost of $800,000 each; one of these M65 artillery pieces was nicknamed Able Annie. Able Annie was fired during tests at Knothole with a backup present nicknamed Sad Sack. The test took place on May 25, 1953 at 8:30am. Codenamed Grable, the test and others where part of the Upshot-Knothole series of nuclear tests that took place in Nevada at Frenchman Flat. Able Annie would end up later earning the nickname  Atomic Annie. The names Able Annie and Atomic Annie likely stem from the vehicles design heritage from the German K5 railroad gun which would end up being nicknamed Anzio Annie after it’s employment against US forces during their landings in Italy. A demonstration model was available to be used in Dwight Eisenhower’s inaugural parade in January 1953.

The M65 was transported by two tractors, one at both ends, each with an engine generating 375 hp. The tractors were capable of communicating by a phone system and could travel at 35 mph. The M65 was 80 feet long and could travel down a paved or gravel road with a width of 28 feet. The vehicle took 15 minutes to setup for use.  The vehicle was capable of a full 360 degree traverse as it sat on a 9 foot circular base plate with jacks. The vehicle had a hydraulic rammer with a back up system using gears; the shells weighed 600 lbs.

Off Topic: Artillery Photos And More

This is off topic but I thought I’d share a selection of photos of Artillery pieces I took while visiting the Texas Military Forces Museum not that long ago. There were several field pieces and at least one anti-aircraft, and one anti-tank piece; from several countries and time periods including examples from France, Russia, and the USA.

 

105 mm (10.5 cm) Cannon on the Sherman and Panzer IV

In the game World of Tanks the available Sherman tanks, the M4, the M4A3E2, and the M4A3E8 as well as the Panzer (PzKpfw) IV are shown as having a 105mm cannon available. In the case of the Sherman, Gun 105 mm SPH M4 L/23; and in the case of the Panzer IV, Gun 10,5 cm KwK 42 L/28. While I’m aware of upgrade programs for the Sherman, while thinking about the Panzer IV this got me wondering about when this would have occurred and where it may have been seen.

Regarding the Sherman I have found that during the Second World War, there was a variant using a 105mm cannon: the M4 Sherman 105mm Howitzer. This variant was used in both an Artillery, and a Tank Destroyer capacity. These tanks were fitted with a modified 105mm M2 howitzer (“1944-U.S.A. M4 Medium Tank (105)”); the M1/M2 being the guns in the M7 Priest Self-Propelled Gun.

While actual Sherman’s using the 105mm cannon were produced and saw action, the Panzer IV with a 105mm (10.5cm) was a different story. The German’s appear to have experimented with a 105mm artillery gun mounted in an experimental demountable turret on a Panzer IV chassis (“Panzer IV”); this experimental design was called the Heuschrecke (“Grasshopper”), a Self-Propelled Gun. A further  experimental design, a tank destroyer nicknamed Dicker Max (Fat Max); it was called the 10.5 cm K gepanzerte Selbstfahrlafette. While the prototype for the  Heuschrecke 10 doesn’t appear to have been sent into combat; the Dicker Max prototypes, both, were sent to the Eastern Front. What is not clear is if two were built and sent to the Eastern Front, or if one was built and sent along with a prototype for the Sturer Emil (Stubborn Emil) which was a comparable vehicle. Quoting the Wikipedia page for the Sturer Emil, the name for the prototypes of the two Sturer Emil units sent to the Eastern Front where “Max and Moritz” (“Sturer Emil”).
