Prior to and following receipt of circuitry designs from the British, various experiments were carried out by Richard B. Roberts, Henry H. Porter, and Robert B. Brode under the direction of NDRC Section T Chairman Merle Tuve. Tuve's group was known as Section T, not APL, throughout the war. As Tuve later put it in an interview: "We heard some rumors of circuits they were using in the rockets over in England, then they gave us the circuits, but I had already articulated the thing into the rockets, the bombs and shell." As Tuve understood, the circuitry of the fuze was rudimentary. In his words, "The one outstanding characteristic in this situation is the fact that success of this type of fuze is not dependent on a basic technical idea—all of the ideas are simple and well known everywhere." The critical work of adapting the fuze for anti-aircraft shells was done in the United States, not in England. Tuve claimed that despite being pleased by the outcome of the "Butement et al. vs. Varian" patent suit (which saved the U.S. Navy millions of dollars), the fuze design delivered by the Tizard Mission was "not the one we made to work!"
