UKMTO's Oct. 23 weekly: 241 Hormuz transits, AIS-observed 47, U.S.-stated about 4:1; 5 attacks (update, Oct. 24, 2026)

Case

UKMTO's weekly overview No. 12, produced Oct. 23, 2026, counted 241 combined Strait of Hormuz transits, about 70% below pre-conflict levels, of which 47 were AIS-observed; U.S.-stated facilitated transits were roughly level at about 4:1 to AIS. The gap with CENTCOM's Oct. 16 claim of about 400 ships persists, and the coverage reviewed shows no CENTCOM explanation of the data or dates behind it.

UKMTO weekly overview No. 12 (Oct. 23, 2026) — documented
UKMTO counted 241 combined transits of the Strait of Hormuz in the week (114 outbound, 127 inbound), versus 254 the week before (125 and 129), about 70% below pre-conflict levels. Strait data run to Oct. 21.
AIS-observed transits rose to 47 from 42, while U.S.-stated facilitated transits were roughly level, at about 4:1 to AIS. The report says the U.S. figures include vessels not broadcasting AIS and that UKMTO cannot independently verify them.
UKMTO reported 5 attacks in the week (2 in the Strait of Hormuz, 3 in the Arabian Gulf), down from 12 the week before. It says it reports only incidents verified through primary sources and that other incidents are known but cannot be verified.

Does the gap with CENTCOM's claim persist? — inferred
Claimed: on Oct. 16 CENTCOM commander Adm. Brad Cooper said about 400 merchant ships transited the strait in the previous seven days.
UKMTO's combined count of 241 is again well below 400 and most of it rests on U.S.-stated figures UKMTO cannot verify, so the gap persists. The two figures may not measure the same thing, and neither source states the other's method.
The coverage reviewed as of Oct. 24 shows no CENTCOM explanation of the data or dates behind the 400-ship and 100-million-barrel figures. The original CENTCOM video post was not opened.

Perspectives

Official position — U.S. Central Command (Adm. Brad Cooper)
CENTCOM's position, as of its Oct. 16 video, is that the U.S. and regional partners control the strait, it is open to commerce, and about 400 ships moved through it in a week. CENTCOM has not published the data or dates behind these figures, and no newer explanation was found.

Note
UKMTO says it cannot independently verify the U.S.-stated transit figures, and CENTCOM has not published the method or dates behind its 400-ship figure, so the gap is unexplained.
