The primary development in the delivery of nuclear weapons by aircraft concerns ihe pfanned lonpi-range o air-la'nched cruise missiles (n-f,CU).

This
analysis: The text appears to be discussing the development and deployment of nuclear weapons, including the use of penetration aids, cruise missiles, and re-entry vehicles. It also mentions the SAL, II treaty and its impact on the technological development of weapons. The text focuses on military technology and strategic defense, suggesting that it may be related to the development of weapons systems.
