It’s a reach, but tempting, to suggest that Australia’s long-term security might even be better guaranteed by spending a few million dollars on towed pinger locators and unmanned Bluefin-21 mini-submarines, with their sonars and cameras, and some serious naval infrastructure to support them, rather than the $20-40 billion currently being contemplated to renew and extend Australia’s aging combat-submarine fleet.
虽然不乏个人猜测意味，但有人提出花几百万购买拖曳式声波发射定位装置及配备声纳和摄像装置的无人驾驶蓝鳍-21小型潜艇并修建为其提供支持的海上基础设施远比目前尚在谋划之中的耗资200-400亿美元升级澳大利亚老化的作战潜艇部队更有利于保障澳大利亚的长期安全。
