2010 MIT article:

Why China's New Supercomputer Is Only Technically the World's Fastest;
Peak performance doesn’t equal sustained performance, and the NVIDIA
GPUs in the Tianhe 1A are especially bad at the latter.

move forward to 2017 MIT article: America Just Can’t Match China’s
Exploding Supercomputing Power

America second? Yes, and China's lead is only growing

China's Tsinghua University dethroned MIT (above) as the top engineering
university in the world in 2015

this is 2011 tutorial on radar (including military) but says it needs
3tflops for really advanced, which was beyond 2011 processing

There are claims that digital signal processing by latest generation of
digital signal processing chips can reduce the number of
transmit/receive pairs in APG-77/79/81/83 by nearly two orders magnitude
w/o loss of capability

significant advances in digital power and processing spurred by
autonomous vehicles, but also useful for military radar (2017 320
t-ops/sec, 100 times 2011 reference).
