A real capability assessment can conclude that you should not buy an aircraft. It defines the requirement, tests it against your terrain, existing capability, budget and procurement authority, and produces a written recommendation you own regardless of who you buy from. An assessment that names a platform on the first page is a proposal.
Almost every integrator in this business offers an assessment. Most of them are a proposal with a cover page — a document that surveys the customer’s situation and arrives, with some inevitability, at the conclusion that the customer should buy what the assessor happens to sell.
A real assessment is distinguishable by one property. It is capable of reaching the conclusion that you should not buy an aircraft at all.
What it should actually contain
A basing and access survey. Which airfields are usable, at what length, on what surface, in what weather, with what fuel supply and what security. This requires visiting them. An assessment written from satellite imagery and a published airfield directory is a desk study, and desk studies miss the fact that the fuel farm has been empty for two years.
An honest read of the existing capability. What the customer already operates, what condition it is in, what proportion is mission-capable on a given day, and what the actual constraint is. Frequently the constraint is not aircraft. It is maintenance, or crew currency, or the fact that the intelligence product has no route to the people conducting operations.
A decision map. Who decides what, on what cycle, with what authority. This is the part most assessments skip and the part that most often explains why the previous capability underperformed. A sensor that feeds a headquarters with no tasking authority over the units in the field produces situational awareness and no effect.
A personnel and training reality check. How many people the proposed capability requires, how many exist, how long the pipeline takes to produce the difference, and whether the customer can retain them once trained. Retention is the question nobody asks, and in several markets it is the binding constraint — a state can train operators faster than it can keep them.
Sustainment cost over a decade, not acquisition cost. Fuel, parts, maintenance, facility power, communications, training pipeline, and the replacement cycle for the ground segment. Presented as an annual recurring figure that somebody in a ministry will have to defend every year, because that is the number that determines whether the capability survives.
What it should cost and how it should be structured
Fixed fee for a defined scope, quoted before the work starts. Two to four weeks is normal for a single-country assessment; longer usually means the scope was not defined.
Credited against the program that follows, if there is one. That alignment matters: it lets the customer treat the assessment as a real evaluation rather than a sunk cost, and it means the assessor is not incentivised to stretch the study.
And the output is a document the customer owns outright, whether or not they proceed. An assessment that remains the property of the integrator, or that is only briefed rather than delivered, is a sales call with a schedule.
The test
Ask the assessor, before engaging: under what findings would you recommend that we do not proceed?
An answer exists for a real assessor. They will describe the conditions — no usable basing, no retention of trained personnel, no sustainment budget, no decision authority connected to the collection — under which they would tell you to fix something else first.
If there is no such answer, you are buying a proposal.
