Glossary

COCO, GOCO & GOGO.

COCO, GOCO and GOGO describe who owns a capability and who operates it. Contractor-owned and contractor-operated is the fastest to field and leaves nothing behind. Government-owned and contractor-operated puts the asset on the national books while a contractor still runs it. Government-owned and government-operated is the only one that produces sovereign capability, and the only one that requires the institution to exist first.

The three models

COCO — Contractor-Owned, Contractor-Operated. The contractor owns the aircraft, employs the aircrew and maintainers, and holds the airworthiness and sustainment burden. The government buys an outcome: flight hours, coverage, intelligence products.

GOCO — Government-Owned, Contractor-Operated. The government owns the asset. A contractor provides crews, maintenance and program management. Common where a government has capital funding but not yet the trained aircrew, maintenance pipeline or airworthiness authority to operate a specialized aircraft.

GOGO — Government-Owned, Government-Operated. The government owns and operates. This is the end state of a capability-transfer program, and it is the only model that produces genuine sovereign capability.

The row that gets overlooked is the last one. A COCO program that runs for eight years and ends leaves the government exactly where it started, having spent more than an acquisition would have cost. That is not an argument against COCO. It is an argument for deciding at the outset which column you are actually buying.

Who carries which risk

The models differ less in cost than in where risk sits, and that is usually the more important question.

Airworthiness. Under COCO the contractor holds the certificate and the legal responsibility for the aircraft’s condition. Under GOCO the government owns an aircraft it may have no authority competent to certify, which means either standing that authority up or contracting for it. Many programs discover this after the aircraft is on their register.

Availability. Under COCO, unserviceability is the contractor’s problem and its cost is inside the rate. Under GOCO the government owns the downtime — an aircraft on the ground is capital not producing, and the sustainment contract determines how quickly that changes.

Obsolescence. A sensor bought in year one is dated by year six. Under COCO the contractor refreshes it because coverage is what was sold. Under GOCO and GOGO the mid-life upgrade is a budget line somebody has to defend, and the programs that did not plan for it end up operating a capability that quietly stopped being competitive.

Attrition of people. Under COCO, crew turnover is invisible to the customer. Under GOGO it is the whole game, and it is why a training pipeline that produces instructors rather than only operators is the difference between a capability and a cohort.

What your procurement authority allows

The choice is often made for you by what your ministry can actually approve.

COCO is an operating expense. It can frequently be approved inside an annual budget by a service chief or a ministry directorate without a capital case, which is why it moves fast.

GOCO and GOGO are capital. They need an acquisition decision, usually a multi-year funding commitment, and in many countries a legislative step. That process is slower and it is also what makes the capability durable — a line in the capital plan survives a change of minister in a way a service contract does not.

This is why the honest first question is not “which model is best” but “which model can you fund, and for how long.”

How programs really move

Few governments start at GOGO and few should. The common path is COCO to establish the operating rhythm and prove the requirement, GOCO once acquisition funding clears, and GOGO once the training pipeline and maintenance organization exist to sustain it.

The GOCO trap

The failure mode is stopping at GOCO indefinitely because the sustainment institution was never built. The government owns an asset it cannot fly without a foreign contractor — which is a worse position than COCO, because the capital is spent, the depreciation is running, and the leverage in any renegotiation has moved to the contractor.

It happens for an understandable reason. GOCO feels like progress: the aircraft is on the national register, it carries national markings, and politically it reads as ownership. The part that did not happen is invisible until the contract comes up for renewal.

The guard against it is writing the next step into the current contract. A GOCO agreement with a defined transfer milestone, competency criteria and progressive handover of maintenance tasks is a route to GOGO. One without those is a subscription with an asset attached, and it will still be a subscription in year eight. That is the same discipline that separates a real contractor logistics support arrangement from a permanent one.

Choosing

Ask what you want to be true in five years. If the answer is “we have coverage,” COCO is correct and cheaper than pretending otherwise. If it is “our own people run this,” then every contract between now and then needs to be written as a step toward it — and capability transfer has to be a deliverable with criteria, not an aspiration in the preamble.

Common Questions

What does COCO stand for?

Contractor-Owned, Contractor-Operated. The contractor owns the asset, employs the crews and maintainers, and carries the airworthiness and sustainment burden; the customer buys an outcome such as flight hours, coverage or intelligence products rather than the equipment itself.

What is the practical difference between GOCO and GOGO?

Under Government-Owned, Contractor-Operated the government owns the asset and a contractor crews, maintains and sustains it. Under Government-Owned, Government-Operated the government does both. The gap between them is not equipment — it is the training pipeline, maintenance organization and airworthiness authority needed to operate independently.

Which model gives a government the most control?

Government-owned and government-operated, by a wide margin, because control follows the ability to operate without anyone else. It is also the slowest to reach and the most demanding of institutional capacity, which is why most programs move toward it in stages rather than starting there.

Which is cheapest?

Contractor-owned has the lowest capital requirement and the highest cost per flight hour; government-owned inverts that. Over a short program contractor-owned usually wins; over a long one it usually does not. The row that gets overlooked is what remains at the end — under contractor-owned, nothing does.

Who should hold airworthiness, and under which authority?

It should be the host nation's military airworthiness authority under any of the three models, and that is worth pursuing from the start rather than treating as a late-stage transfer step. The reason is the configuration: a mission aircraft carrying a belly turret, hardpoints, an antenna farm, extra electrical generation and operator stations is awkward to certify through a civil aviation authority, which is not structured to approve that kind of modification and will require an engineering substantiation and certification basis that can take longer than the program has. A military authority assesses those modifications routinely. Where the host authority is not yet able to, a contractor can hold it in the interim — but that is a bridge, not the destination.

Why do programs get stuck at GOCO?

Because GOCO feels like progress — the aircraft is on the national register with national markings — while the sustainment institution that was supposed to follow never gets built. The capital is spent, depreciation is running, and the government owns an asset it cannot fly without a foreign contractor. That is a weaker position than COCO, because the leverage in any renegotiation has moved.

Which model should we choose?

Ask what you want to be true in five years. If the answer is coverage, COCO is correct and cheaper than pretending otherwise. If it is that your own people run this, every contract between now and then has to be written as a step toward it, with transfer as a deliverable carrying competency criteria rather than an aspiration in the preamble.
