The somewhat disgruntled minutes6 of the meeting of the Chiefs of Staff Committee of the War Cabinet, on 15 February 1943, explained the position:
1943年2月15日，在战争内阁委员会代表会议的会议记录上略有不满地记录：
THE COMMITTEE had before them a Memorandum by the British Joint Communications Board on a proposal for the installation by the Americans of a highly secret apparatus for telephone communication between the United States and London.
英国合作交流委员会向本委员会提交了一份备忘录，提议由美国部署一套高度保密的设备，用于英美之间的电话通信。
THE COMMITTEE were informed that Major Millar, a US officer specially sent over for the purpose of installing the apparatus, had now arrived.
委员会被告知，负责设备部署的美国官员米勒少校现在已经抵达。
His instructions were to place it in some building where it would be exclusively under American control, though it could be used by high officials in the British Government.
他打算将机器部署在由美国严格控制的建筑中，英国政府的高层官员可以使用。
There were only two other sets, one of which was being installed in the White House, and one in the War Department in Washington.
该设备除此之外只有两套，一套安装在白宫，另一套在五角大楼。
No more sets could be produced for eight or nine months.
八九个月之内无法部署更多。
The following were the main points in the discussion:
以下是讨论的要点：
a) Security. It was noted that the only Englishman who had yet been able to examine the apparatus was Dr Turing of the Government Code and Cypher School.
1、安全性。会议指出，目前只有政密学校的图灵博士对该设备进行过考察。
In view of the fact that conversations relating to British operations would undoubtedly take place over the secret telephone,
鉴于该加密系统传输的信息将涉及英国的军事行动，
we had a legitimate interest in finding out whether the new apparatus could really be considered one hundred per cent secure.
因此我们合理地希望考察这种新型设备是否真的可靠。
It was thought that this could best be cleared up by the Joint Staff Mission in Washington, where ample technical talent was available.
我们认为，此项工作最好由合作人员代表团来负责，他们拥有大量的技术人才。
