The Abrams case closes — a delivery ladder completed — Key Events — Taiwan Strait

What happened

The third and final batch of M1A2T Abrams main battle tanks arrives in Taiwan at the end of April 2026, completing that Foreign Military Sales case. The published backlog of notified-but-undelivered US cases falls from roughly $32.0bn to $29.72bn on its completion.

Vigil records this because a completed case is the only way to see the whole ladder at once — notification, contract, delivery, and entry into service — and because the backlog figure moving is the ladder made visible in a published number. The contrast cases matter as much: 500 Stinger missiles notified in 2015 and 2019 were still undelivered in May 2026, Paladin howitzers notified in December 2025 are now reported as delivering in 2030, and other cases are held by an appropriation dispute in Taipei rather than by production. Delivery is not readiness, and this record asserts none.
