Mr. Chair, there is a lot in that question to unpack.
Firstly, NORAD modernization is moving ahead. It's focused on the air domain for the most part, with investments in sensors to replace the North Warning System specifically with over-the-horizon radar. It's focused on command and control systems, which are very important to bring all those sensors together so that we have decision-quality information. It's focused on infrastructure specifically, so that our forward operating locations in the north are ready to receive more aircraft. It's also focused on research and development. As the pace of technological change is accelerating, we have to invest more into research and development so that we can keep pace.
