Russia's successful test of its Avangard hypersonic glide missile will almost certainly ignite a full-on arms race panic in the US, according to German newspaper Die Welt. As we noted earlier this week, the missile was launched from a base in the southern Ural Mountains on Wednesday and successfully hit a practice target on Kamchatka 3,700 miles away.
Still, though it has lagged behind in hypersonic weapons development, the Pentagon is struggling to catch up. The Defense Advanced Research Projects Agency revealed this week that it is seeking new designs for cooling super-hot leading edges of hypersonic vehicles as they rip through the atmosphere as it works to develop its own hypersonic missile. Considering that the New START arms control treaty between the US and Russia will likely expire without an agreement to renew by 2021, that task is probably taking on a renewed urgency.
