Fresh images of the classified B Raider bomber , released Jan. The Air Force did not say whether the new images, created by Northrop Grumman, have been adjusted to conceal any details. The images released Jan.
Details about the U. Air Force's new, secret B Raider stealth bomber have so far been limited, but some have emerged since the service announced that it had picked Northrop Grumman to build it However, since then, there has only been a single piece of official concept art of the aircraft — that is until now. On Jan. In March , the Air Force announced that Ellsworth would be the first base to host an operational Raider squadron. Whiteman and Dyess, which presently host B-2 Spirit stealth bombers and B-1 Bone supersonic bombers, respectively, are also set to get Bs after Ellsworth. Though the renderings certainly still lack a certain level of detail, the B-2's influence on the B , including the position and style of the cockpit, is clear. There are a number of other very important features that are also now more visible. The B's nearly flush inlets and blended conformal engine nacelles are more apparent now, a key low-observable characteristic that is somewhat revolutionary for the design.

Metrics details. Improving the design and implementation of evidence-based practice depends on successful behaviour change interventions. This requires an appropriate method for characterising interventions and linking them to an analysis of the targeted behaviour. There exists a plethora of frameworks of behaviour change interventions, but it is not clear how well they serve this purpose. This paper evaluates these frameworks, and develops and evaluates a new framework aimed at overcoming their limitations. A systematic search of electronic databases and consultation with behaviour change experts were used to identify frameworks of behaviour change interventions.
As part of the Long Range Strike Bomber program LRS-B , it is to be an advanced very long-range, large, heavy-payload stealth intercontinental strategic bomber for the USAF, able to deliver conventional and thermonuclear weapons. The bomber is expected to enter service by A request for proposal RFP to develop the aircraft was issued in July A media report states that the bomber could also be used as an intelligence gatherer , battle manager , and interceptor aircraft. Air Force Global Strike Command expects that B bombers will be the minimum ordered and envisions some — bombers in service. In April , it was reported that the U. In July , the U. Air Force stated they would not release the estimated cost for the B contract with Northrop Grumman. The Air Force argued releasing the cost would reveal too much information about the classified project to potential adversaries.
