A ~$4.65B contract that begins before the price is settled — the undefinitized contract action (Lockheed Martin, Navy)

1The abbreviation UCA

In defense acquisition, UCA is used as shorthand for an undefinitized contract action — an arrangement authorizing work to begin before price and terms are settled. Ordinary procurement agrees scope and price before a contract is signed. But waiting to start can miss an operational requirement, or the scope itself may still be under negotiation. In those cases a ceiling is set, work begins, and the price is definitized afterwards.

2What is being borrowed against

The benefit of this form is time. Responding to a design change, an urgent modification, or securing a supply chain are all situations where the delay itself costs money or capability. There is a price for it. Work advancing before the price is set means that, at the moment of negotiation, costs have already been incurred, which weakens the government's bargaining position.

That is why such actions customarily carry constraints — a deadline for definitization, and a cap on the share that may be spent before it.

3What the record shows

The value is about $4.65 billion cumulative, and the period runs from November 2018 to April 2027. Recorded outlays are about $189.77 million, but public outlay fields can be incompletely recorded and cannot be read as an execution rate. The scope is one line, with no aircraft type, no description of the work, and no date of definitization. This site does not write beyond what is recorded.

4Buying time and giving up negotiating position

What this form buys is time. Answering a design change, an urgent modification, securing supply — there are many situations in which the delay itself is the loss of money or capability. That time comes at a price.

That is why such actions customarily carry limits on when they must be definitized and on the share that may be spent before then. It is easy to be drawn to the size of an amount, but whether that figure is an agreed price or a ceiling set before negotiation makes it a different thing entirely.
