A typically egregious example of illiteracy by editor writing headlines. The text by article author doesn't say anything inaccurate to my knowledge, but editor-chosen headline says 'jets' when describing a helicopter + jet fighter; says they 'vanished' when both ditched and had crews rescued.

The Question I Asked After Watching House of Dynamite
Missile inbound? Don’t panic or go outside. CEP, yield, and misfires matter—shelter fast. One warhead isn’t Armageddon; smart steps hugely improve survival.

Shield AI says it's developing an X-BAT drone fighter last week intended to take off and lands vertically using an F-16 turbofan targeting greater range, speed, stealth and autonomy than current loyal wingmen. Read on for thoughts on underlying theory/application and challenges to realizing concept.

Saw old piece of mine on AIP/diesel-electric submarines cited here arguing their cost-efficiency for littoral sea denial missions. An interesting debate, but current events point to their risks! For U.S. they're a forward-basing, alliance commitment asset-and current admin is 100% opposed to that!

The Pentagon is reequipping infantry brigades with M1301 Infantry Squad Vehicles-Chevy pickup trucks-more expensive than Humvees yet leaving troops far more exposed. Attached to combat squads but not intended for combat, an officer shares why he fears they're bad at both. DoD testers seem to agree.
