T-37A tank

The T-37A was a Soviet amphibious light tank. The tank is often referred to as the T-37, although that designation was used by a different tank which never left the prototype stage.The T-37A was the first series of mass-produced fully amphibious tanks in the world.

The tank was first created in 1932, based on the British Vickers tankette and other operational amphibious tanks. The tank was mass-produced starting in 1933 up until 1936, when it was replaced with the more modern T-38, based on the T-37A. Overall, after four years of production, 2552 T-37A’s were produced, including the original prototypes.

In the Red Army, they were used to perform tasks in communication, reconnaissance, and as defense units on the march, as well as active infantry support on the battlefield. The T-37A were used in large numbers during the Soviet invasion of Poland and in the Winter War against Finland. The T-37 A was also used by the Soviets in the beginning of the Great Patriotic War, but most of them were quickly lost. Surviving tanks of that type fought on the front lines until 1944, and were used in training and auxiliary defense until the end of World War II.

T.37

T.37 is an ITU standard which deals with sending fax messages using email. It is also referred to as "iFax", "Internet Fax", or "Store-forward-fax".

A fax machine supporting T.37 will send a fax to an email address by converting the document to a TIFF-F image, attaching it to an email (using the MIME format), and sending the document (using SMTP). The destination fax receives the email and prints the attached document.

7.2-Inch Demolition Rocket

The 7.2-Inch Demolition Rocket, also known as the T37, was a 7.2-inch (180 mm) rocket developed and used by the United States military during World War II. Derived from the "Mousetrap" anti-submarine rocket, it was intended for use in demolishing concrete bunkers and fortifications, and saw use from August 1944.

Development

The 7.2-Inch Demolition Rocket was developed by Section L of the National Defense Research Committee, located at Caltech, in late 1943 as a modification of the existing "mousetrap" (7.2-Inch ASW Rocket) rocket for use against heavily fortified ground targets. Assigned to the United States Navy for development and production in July 1944, two versions of the rocket were produced; the T37 HE Demolition Rocket and the T21 Chemical Warfare Rocket. An additional high-explosive rocket, the T24, was planned, but was dropped in favor of the T37. The rockets utilized a standard 2.25-inch (57 mm) rocket motor, fitted with a larger-diameter warhead; a longer-ranged version utilizing a 3.5-inch (89 mm) motor was also produced.
