USAF’s Future Fighter Plan May Limit Growth, Study Says
By Jen DiMascio
The U.S. Air Force's plan for acquiring future fighter aircraft may crimp the service's ability to grow in the future, a study of the USAF's force structure plans indicates.
The study, “The Air Force of the Future,” compares the service's force structure plans during times of peak budgets—in fiscal 2020 and fiscal 1985. In fiscal 2020, a budget of $205 billion could support 5,300 aircraft. This is a little more than half of the number that the same amount of money, adjusted for inflation, could support in 1985—9,400. The same holds true for the number of personnel, the report says. It was released Oct. 29 by Todd Harrison, director of the Aerospace Security Project at the Center for Strategic and International Studies, which examined three different studies of the size of the future force.
As part of the report, Harrison drills further into the Air Force's spending habits to find that one factor underlying the inability to afford a larger force is the increase over time in operation and maintenance costs.
“The average O&M cost per plane is 74% higher today in real terms than in fiscal 2001,” the report says.
Looking more closely at maintenance costs, he finds that the most expensive aircraft to operate are the smallest fleets, such as the Boeing E-4 Advanced Airborne Command Post aircraft, the Northrop Grumman E-8 Joint Surveillance Target Attack Radar System and Northrop's B-2 bomber.
“This is because the fixed costs of operating the fleet are distributed across more aircraft in large fleets, which brings down the overall ownership cost per plane,” the report says. “The data suggest that the Air Force could reduce operating costs by divesting aircraft that are maintained in small numbers in the current inventory and consolidating the capabilities they provide into common multimission platforms.”
Air Force acquisition chief Will Roper is recommending an acquisition strategy dubbed the “digital century series.” It aims to build new fighter aircraft designed to last 3,500 flight hours in batches of hundreds, rather than the current model of pursuing advanced technology for an aircraft type that will last for decades.
But Harrison estimates that the operation and sustainment cost of sustaining five different aircraft types of 72 aircraft, or 360 total aircraft, would cost about the same as sustaining 1,800 aircraft of the same type.
“That's something the Air Force has got to consider,” Harrison said. “With the digital century series approach, they may end up with a bunch of small fleets and may limit the ability of the Air Force to grow in the future.”

BAE Systems progresses digital shipyard plan for Australia
Jon Grevatt, Bangkok BAE Systems is moving ahead with its programme to transform naval shipbuilding facilities in South Australia into a digital shipyard that will support the construction of the Royal Australian Navy's (RAN's) new Hunter-class frigates. The company was selected for the nine-ship frigate programme earlier in July – under the AUD35 billion (USD26 billion) Sea 5000 project – and will build the ships in collaboration with state-owned naval shipbuilder ASC from late 2020. The Hunter-class is a variant of BAE Systems' Type 26 frigate design, which the company is also building for the UK Royal Navy (RN). While contract negotiations are ongoing between BAE Systems and the Australian government to finalise the details of the Sea 5000 project, work to prepare Adelaide-based ASC's shipbuilding facilities is under way, with BAE Systems already committed to investing at least AUD100 million (USD74 million) to develop the proposed digital shipyard at which the ships will be built. Nigel Stewart, BAE Systems managing director for the Sea 5000 project, said the digital shipyard will be supported by an “unprecedented” transfer of intellectual property and technical data that will facilitate the development of local capability to both build and maintain the Hunter-class frigates over its 30-year life span. “The digital design of one of the world's most sophisticated ships will support the development of a continuous naval shipbuilding capability in Australia, ensuring that local industry can build the fleet of nine future frigates,” said Stewart. “The digital design will also ensure they can be upgraded and supported during their decades of service.” He added, “This is an unprecedented transfer of intellectual property that will also include all ship parts, materials, and systems used to build the Type 26 frigate. With this knowledge, Australian industry will gain the know-how needed to both build and optimise the ship over its life, potentially improving its flexibility and performance with bespoke local innovation and technology.” http://www.janes.com/article/81959/bae-systems-progresses-digital-shipyard-plan-for-australia
