The Best National Security Gossip

YOU’VE GOT EMALS – NO WAIT! President Trump has ordered the Pentagon to figure out how to replace the Ford-class carrier’s electromagnetic catapults (called EMALS) with the steam technology they replaced — starting with CVN-81, the future USS Doris Miller. USNI News says the memo gives the Pentagon 60 days to produce a plan, including timelines and costs. EMALS replaced the steam catapults that launched carrier aircraft for seven decades. The first three Fords — Ford, John F. Kennedy and Enterprise — reportedly would keep it; but Doris Miller and subsequent carriers would go backward. The irony: according to Newsweek the [...] More

State Secrets

Artificial intelligence is transforming cyber warfare - and former NSA Director and U.S. Cyber Command Commander Gen. Paul Nakasone says the speed of that transformation demands a new approach to America’s defense.

In this episode of The Cipher Brief’s State Secrets podcast, Suzanne Kelly sits down with Gen. Nakasone to discuss how AI is reshaping offensive and defensive cyber operations - and why increasingly autonomous systems could fundamentally change the role humans play in cyber conflict.

They examine China’s penetration of U.S. telecommunications and critical infrastructure, cyber threats from Iran, Russia and North Korea, the growing ransomware threat, the race to prepare for quantum computing, and what Ukraine is teaching the world about autonomous warfare.

Gen. Nakasone also explains why America’s intelligence capabilities remain a critical competitive advantage, why defending critical infrastructure requires deeper partnerships between government and the private sector, and what national security leaders should be watching now.
