On 12-Mar, David talked about military weapons being made obsolete by newer models. Here's the gist of his talk:
Recent tensions with North Korea have lead to talk
of increasing the US's nuclear defenses. Russia has responded by
announcing a new set of weapons designed to defeat nuclear defenses.
Russian weapons includes a Samat ICBM launched hypersonic delivery
vehicle. The Kinzhal hypersonic Kenzhal, designed to be launched from a
MIG-31, was tested last week. They also announced a tomahawk-style
hypersonic GLCM with a "nuclear booster", it is unclear how the booster
works. A new underwater drone was announced with a 100 MT warhead and
1000 mile range, four of which can be carried on an Oscar-class sub.
The US has also announced plans for new weapons systems. An RFP for a
next generation manned fighter to replace the F-22 and F-35 was
announced, based on concerns over China's J-31. The B-21 program is
underway to replace the B-2. It can be operated manned or unmanned. The
A-10 will be replaced by a new Intelligence, Surveillance, and Light
Attack (ISL) aircraft. Most likely, this will be the Cessna Scorpion, a
new light jet that can be flown manned or unmanned. Data for this came
from multiple sources.
