Britain’s E-3D Sentry Airborne Warning and Control System (AWACS) is based on Boeing’s 707 family, and its ability to see and direct air operations within hundreds of miles provides vital strategic support. Since its introduction in 1992, the RAF’s fleet of 7 E-3s has been used in every major UK military operation, including Bosnia, Kosovo, Afghanistan, Iraq, and Libya.
That availability depends on effective maintenance, and the UK MoD has a new approach. It’s meant to give them more flyable planes, while costing less money. The new Sentry Whole Life Support Program (WLSP) began in August 2005, when Northrop Grumman won a 20-year, GBP 665 million (then $1.2 billion) contract. Under that contract, NGC’s team is providing aircraft maintenance and design-engineering support services through 2025, in order to improve availability and reduce overall ownership costs. As is typical of recent British contracts, the government has chosen a public-private partnership founded on an unusual military combination: fixed base costs, and guaranteed time in-service percentages for the planes.
