Reduce Advanced Amphibious Assault Vehicles and their replacements

Research notes

Two-part ask (the AAVs and their replacements). The AAV side was settled before the window by Force Design; the replacement side (the Amphibious Combat Vehicle) was funded, not reduced, inside it.

• The AAV reduction is marked Already true, with the contrary in-window funding attached as Evidence on the same event, as action that moved the other way.

• Confirmed 2026-09-01, Already true kept. Two questions were open and both resolve in favor of keeping it. First, the in-window reconciliation money: the Already-true rule as amended 2026-09-01 strikes the “with nothing happening inside it” clause, so action inside the window goes in the note and does not defeat an Already-true finding that describes the world on 2025-01-20. Second, the replacement limb: printed p. 116 is a page of endorsements of decisions Force Design had already executed, and the reduction of Amphibious Vehicle Companies from 6 to 4 — the only figure CRS R47614 v7 gives, at its Force Design bullet list — cuts both the AAV fleet and the replacement buy those companies would field, so neither limb was outstanding on 2025-01-20. CRS gives no separate ACV program-of-record figure; evidencing the replacement limb in its own right was left as a further reading, not a reason to drop the finding.

• CRS R47614 v7 (2025-11-24) is the source for the 6-to-4 company reduction.

• The replacement limb now has its own reading, and it is negative (2026-09-03). The note above left a separate ACV program-of-record figure as a further reading. That read has been done: marines.mil now serves the document, and the Commandant’s October 2025 Force Design Update (5.5 MB, created 2025-10-21) was fetched and read in full. It says:

  AMPHIBIOUS COMBAT VEHICLE (ACV). The ACV is our replacement for the Amphibious Assault Vehicle (AAV). By the end of this year, we will have fielded 257 ACV personnel carriers and mission control variants across the three MEFs, 41 percent of our total acquisition objective. ACVs are in the fight.

  “41 percent of our total acquisition objective” is the Commandant stating that the objective is intact and the program is 59 percent short of it — not that the buy was cut. The word “divest” appears zero times in the document, as do “eliminate”, “disestablish” and “deactivate”. So the replacement limb of the Quote is affirmatively contradicted by an in-window Primary source, not merely unevidenced. Already true is kept on the AAV limb as the note above sets out; the ACV finding is contrary in-window action and is cited as Evidence on this event, which is where it now sits.

• Checked 2026-09-06: Already true stands, and this one was argued both ways before it was decided. The Already-true rule as amended 2026-09-06 withdraws Already true where the ask’s object is undone inside the window, so this item was tested limb by limb against a fresh read of the Commandant’s October 2025 Force Design Update (marines.mil, 5.5 MB, 667 lines) and CRS R47614 v7, both re-fetched 2026-09-06.

  • The reduction limb is untouched. No AAV has been returned to waterborne operations and no amphibious vehicle company has been re-established; the 6-to-4 cut stands. There is nothing here to undo.
  • The case for withdrawing Already true is the replacement limb. Inside the window Congress put $241,000,000 into “the development, procurement and integration of Marine Corps amphibious vehicles” (P.L. 119-21 § 20010(15)) and authorized $48,280,000 of ACV military construction at Camp Pendleton, and the Commandant reports the ACV at “41 percent of our total acquisition objective”. Read one way that is money buying more of the thing the Quote wants fewer of.
  • The case for keeping it, which is the reading taken. The amendment asks whether the object has ceased to be in the asked-for state, and the Commandant’s own words are that the total acquisition objective is unchanged — the same number of replacements as on 2025-01-20, 59 percent of them still undelivered. Money that funds delivery against an objective nobody enlarged does not increase the number of replacements; it is the program continuing at the size it already was. Nothing moved the object out of the state it was in when the window opened, so there is no reversal to find — a change of degree, and on the reduction limb not even that.
  • What this does not settle. The replacement limb’s pre-window satisfaction rests on the inference that cutting Amphibious Vehicle Companies from 6 to 4 also cut the replacement buy those companies would field, and “41 percent of an unchanged total acquisition objective” strains that inference. That is a challenge to whether Already true was ever right — whether anything was outstanding on 2025-01-20, decided 2026-09-01 — not the reversal question this check asks, and the 2026-09-06 amendment does not reopen it. It remains an open question. Contrast #219 on the same printed page, whose Already-true finding was withdrawn in the same check: there the Corps directed new structure into the object.
