During World War I the company manufactured shell fuzes and aircraft instrumentation, and during World War II built aero-engines, bomb sights and code-breaking machines, including the American bombe designed by Joseph Desch.

This machine, known as a bombe, was initially conceived by Alan Turing, but the actual machine was designed by BTM chief engineer Harold ' Doc ' Keen, who had led the company's engineering department throughout the 1930s.

The bombe was an electromechanical device used by British cryptologists to help decipher German Enigma-machine-encrypted signals during World War II.

The initial design of the bombe was produced in 1939 at the UK Government Code and Cypher School at Bletchley Park by Alan Turing, with an important refinement devised in 1940 by Gordon Welchman.

This regularity was exploited by Welchman's " diagonal board " enhancement to the bombe, which vastly increased its efficiency.

Turing, a brilliant mathematician, developed a machine called the “ bombe ”, which speeded up the deciphering process by trial and error — a crucial development for the codebreakers.

Welchman envisaged an enhancement to Alan Turing's improved design of the Polish electromechanical Enigma-cipher-breaking machine, the bombe.

In the words of Gordon Welchman "... the task of the bombe was simply to reduce the assumptions of wheel order and scrambler positions that required ' further analysis ' to a manageable number.

Other Escoffier creations, famous in their time, were bombe Néro ( a flaming ice ), fraises à la Sarah Bernhardt ( strawberries with pineapple and Curaçao sorbet ), baisers de Vierge ( meringue with vanilla cream and crystallised white rose and violet petals ) and suprêmes de volailles Jeannette ( jellied chicken breasts with foie gras ).

Building up these relationships into such a diagram provided the menu from which the bombe connections and drum start positions would be set up.

The function of the bombe was to discover some of the daily settings of the Enigma machines on the various German military networks: specifically, the set of rotors in use and their positions in the machine ; the rotor core start positions for the message — the message key — and one of the wirings of the plugboard.

He devised a number of techniques for breaking German ciphers, including the method of the bombe, an electromechanical machine that could find settings for the Enigma machine.

The working rebuilt bombe at Bletchley Park museum.

The bombe identified possible initial positions of the rotor cores, and the stecker partner of a specified letter for a set of wheel orders.

The bombe was an electro-mechanical device that replicated the action of several Enigma machines wired together.

The standard British bombe contained thirty six Enigma-equivalents, each with three drums wired to produce the same scrambling effect as the Enigma rotors.

A bombe could run two or three jobs simultaneously.

If the menu contained 12 or fewer letters, three different wheel orders could be run on one bombe ; if more than 12 letters, only two.

Unlike Enigma rotors, the bombe drums had two sets of input and output contacts, so that they could be connected together in series.

The bombe drums were arranged with the top one of the three simulating the left-hand rotor of the Enigma scrambler, the middle one the middle rotor, and the bottom one the right-hand rotor.

Typically, there were many false bombe stops before the correct one was found.

A graph of the letters of a crib and ciphertext expressed as a graph to provide a menu which specifies how to set up a bombe run.

A bombe run involved a cryptanalyst first obtaining a crib — a section of plaintext that was thought to correspond to the ciphertext.

Once a suitable crib had been decided upon, the cryptanalyst would produce a menu for wiring up the bombe to test the crib against the ciphertext.
