Discussions are still underway, but preliminary information was exchanged.
A draft document was prepared which, when completed by the Soviet side, will give these requirements, among other things. It became clear in the discussions that neither side has actually built the necessary hardware, not even in prototype form. Neither side can wait for the other to produce a prototype before proceding with its own design. Therefore, regardless of which side provides requirements to which, they will have to be based on estimated rather than measured performance. In this memo, I attempt to provide a preliminary set of minimum requirements for each side.
