Unclassified Facts on the Air Force Penetrating Bomber
Amy Butler - AVWEEK
Provide industry executives the unclassified facts on the new penetrating bomber program.
- Based on Secretary of Defense direction, the Air Force (AF) is developing a new penetrating bomber.
- The new penetrating bomber will be a component of the joint portfolio of conventional deep-strike capabilities.
- The new penetrating bomber will be highly survivable, nuclear capable, and designed to accommodate manned or unmanned operations
- The new penetrating bomber will be able to employ a broad mix of stand-off and direct-attack munitions.
- The total annual budget by appropriation (i.e., RDT&E, Production) is unclassified.
- The Air Force plans to deliver the initial capability in the mid-2020s.
- The new program will leverage mature technologies and constrain requirements based on affordability
- The new program will focus on affordability: unit cost target set to inform design/requirement trades and ensure sufficient inventory.
- The Air Force is projecting to build a fleet of 80-100 aircraft.
- The new program will employ enhanced security measures and be protected by a Special Access Program.
- All other details are classified to protect operational advantages and the nation's investment in critical technologies and capabilities.
- For further information, contact the Procuring Contracting Officer (PCO) or the Program Security Officer (PSO)

Launch Preparations Move Forward
Thu, 30 Jun 2011 07:57:48 AM CDT
Preparations at NASA's Kennedy Space Center in Florida are moving forward as space shuttle Atlantis' liftoff on July 8 nears. Today, technicians at Launch Pad 39A will pressurize Atlantis' main propulsion system following the closure yesterday of the spacecraft's payload bay doors.
The STS-135 crew will participate in preflight interviews from NASA's Johnson Space Center today. Briefings about this final mission of the Space Shuttle Program will air live on NASA TV throughout the day and also can be seen online at www.nasa.gov/ntv.

The U.S. government sent a plane equipped with radiation monitors over the Los Alamos nuclear laboratory Wednesday as a 110-square-mile wildfire burned at its doorstep, putting thousands of scientific experiments on hold for days.
Lab authorities described the monitoring as a precaution, and they, along with outside experts on nuclear engineering, expressed confidence that the blaze would not scatter radioactive material, as some in surrounding communities feared.
Lab authorities described the monitoring as a precaution, and they, along with outside experts on nuclear engineering, expressed confidence that the blaze would not scatter radioactive material, as some residents feared.
"Our facilities, our nuclear materials are all safe, they're accounted for and they're protected," said lab director Charles McMillan.
The twin-engine plane, which can take digital photographs and video as well as thermal and night images, was sent to New York City to take air samples after the Sept. 11 terrorist attacks. It has flown over wildfires and areas damaged by Hurricane Katrina. It monitored the 2002 Winter Olympics in Salt Lake City. It also helped locate debris from the disintegrated space shuttle Columbia shuttle.
"It can look for a wide variety of chemical constituents in a plume and the plumes can originate from fires, from explosions, from a wide variety of sources," said lab spokesman Kevin Roark.
And in a testament to the sophisticated research done at Los Alamos, the plane was developed with technology from the lab, the desert installation that built the atomic bomb during World War II.
The pillars of smoke that can be seen as far as Albuquerque, 60 miles away, have people on edge.
The fire has also cast a haze as far away as Kansas. But officials said they analyzed samples taken Tuesday night from some of the lab's monitors and the results showed nothing abnormal in the smoke.
Anti-nuclear groups have sounded the alarm about thousands of 55-gallon drums containing low-grade nuclear waste - gloves, tools and other contaminated items - about two miles from the fire. Lab officials said it was highly unlikely the blaze would reach the drums, and that the steel containers can in any case withstand flames and will be sprayed with fire-resistant foam if necessary.
Kevin Smith, site manager for the National Nuclear Security Administration, said the lab's precautions have been scrutinized by dozens of experts. The lab has been shut down since Monday, when all of the city of Los Alamos and some of its surrounding areas - 12,000 people in all - was evacuated. The fire has held up research on such topics as renewable energy, AIDS and particle physics.
"We have 10,000 experiments running at the same time," said Terry Wallace, science chief at the lab. "We'll have to do an analysis to see what's been affected and how it's been affected."
The plane is just one part of an elaborate air monitoring network surrounding the lab. The lab and the New Mexico Environment Department have dozens of monitors on the ground throughout the region. McMillan said four high-volume air samplers were deployed Tuesday and more were on their way Wednesday.
Some experts familiar with the Los Alamos lab said there is no reason to fear that flames will scatter radiation.
"The nuclear materials are secure," said Penn State University nuclear engineering professor Barry Scheetz, who has served on National Academy of Sciences nuclear review boards and has been to Los Alamos several times. "There's multiple redundancy in the protection of this material. It's not just laying out. It's not there so that a fire is going to disrupt it there and disperse it. The procedures that are in place to protect this material are tremendous."
He added: "The U.S. government, the Department of Energy, has spent literally hundreds of millions of dollars for scenarios that are so unlikely to occur that it is even ridiculous to think about."
