Appendix 2 to Operations Order "Monsoon"
V. Communications Instructions:
21) Wireless traffic to be cleared in accordance with Standing War Orders - Communications Regulations (N.B. U-boats).
Wireless discipline see paragraph 15 - 17 of this operational order.
22) A special U-boat (wave-length) system "India", is to be inaugurated for communication between home (stations) and units operating in the Indian Ocean.
The order for this, included in the appendix is drafted as a Standing Operational Order B.d.U. (Comm. Regs.). When this system is put into force, the draft is to be inserted in the Communications Regulations for U-boats as a Standing War Order. The number will be given. If alterations are necessary boats will be informed by W/T.
23) There is as yet little experience of wireless traffic for the operations area. The cooperation of the boats, therefore, is expected.
a) Exploitation of every chance of reliable interception.
The use of a special very long wave high-power transmitter is probable.
The operating of special short wave program times is proposed.
b) Most extensive use of Wireless system "B" (Standing War Order 206 App. 2) and alternative frequencies for the sending of news.
As far as can be seen, wireless system "B" is particularly suitable for the operational area, especially if home reception is bad on the ordered system.
c) Wireless relay service and the exploitation of possibilities of U-boats group system (Standing War Order 207), is to be particularly observed especially in combined operations. Always attempt to contact the Command on the home wave lengths.
d) Experience of reception conditions in the operations area are of special importance to the control station for the clearing of wireless services. Observations on this point are therefore to be added to other messages. Improvement is only possible in this way.
The keeping of a S/S list for all short and very long waves observed (also on outward and return passage) is very important especially in the operations area as the later evaluation by scientific departments is of great value in the improvement of all U-boat wave bands.
24) Cypher and recognition signal tables and line indicators for the frequency tables for maximum period, also excepts from the frequency tables A - D January 1942 issue are to be taken.
25) For change of recognition signals outside Europe, area according to Recognition Signal Directive paragraph 110, also except from Recognition Signal Directions Overseas edition (Standing Operational Order 222) suitable for call sign exchange with the tanker "Brake".
(See also paragraph 20 of this Operational Order)
The carrying out of call sign exchange with Japanese Naval Forces or aircraft likewise on approaching Penang will be ordered by W/T.
26) When operating in shallow water, preparations must be made for the destruction of cypher material, place red printed matter so that the water can reach it. (See Standing War Order 231 Section B)

f) Japanese physicist Yoshio Nishina met his with army liaison officer Major General Nobuji and reported that he expected to be successful with the nuclear research project. He noted that 10 kilograms of uranium-235 of at least 50% purity to create an atomic bomb, but he needed a large cyclotron to conduct experiments to confirm this theory. Nobuji promised further funding.
