スパイ兵器は極めて重要だ。
情報のあるなしで全く戦況が変わる。
日々、情報収集に努め、もしも戦うことがあれば備えておくというのが基本。

US plans for hypersonic robot spy plane revealed
Lockheed Martin has begun work on a successor to the supersonic Blackbird SR-71 spy plane.
The unmanned SR-72 will use an engine that combines a turbine and a ramjet to reach its top speed of Mach 6 - about 3,600mph (5,800km/h).
Like its predecessor, the SR-72 will be designed for high-altitude surveillance but might also be fitted with weapons to strike targets.
Lockheed said the aircraft should be operational by 2030.
Jet engines
The SR-72 is being developed at Lockheed Martin's Skunk Works R&D centre in California that designed and built the original Blackbird.
That aircraft first flew in 1964 and was a mainstay of US Air Force spying and surveillance work until 1998. It typically flew at altitudes of 24,000m (80,000ft) and could reach speeds of Mach 3.
廃止された、コンコルドのような趣。
