The second-generation radar had already become operationally significant, equipping both the navy and the army on a large scale, and constructing radar bases on land and along the coast became the subsequent task for the radar laboratories.
In some critical areas, including areas of strategic importance, it was necessary to build detection radar bases.
Don't underestimate the second-generation radar with its maximum detection range of only 56 kilometers; sometimes, that 56 kilometers could prove to be the decisive factor.
But then again, Arthur had higher expectations for radar technology.
Given the current global situation, no one was clear when the World War would break out.
Only by mastering more advanced radar technology earlier and applying it across the naval, land, and air forces, could the security of the territory and the strength of the military be guaranteed.
Although radar could only cover a little area, it was still very useful in narrow and long strips of land.
