US fast-tracks B61-13 nuclear gravity bomb amid rising threats

The US is expediting production of the B61-13 nuclear gravity bomb—originally slated for 2026—to counter evolving global threats. With a yield of 360 kilotons and modern safety features, it is set to replace older B61-7 models without increasing the overall nuclear stockpile. The move aligns with US strategic goals to deter adversaries like China and Russia.
