DefenseOne上月发文,谈及LRS-B飞机时提及其能力
新轰炸机不仅仅是一款轰炸机,由于传感器和计算机的成本已经比过去大为减少,这使得空军能够给新轰增加额外的功能。其机体中埋设天线、摄像镜头,和其计算处理能力相配合,使此飞机也成为一架“长程传感器”, 具有侦查和空中指挥能力。
除了能装载大量炸弹外,新飞机还可以:
情报收集
过去十几年空军已经给老轰炸机安装情报搜索装备,B-1和B-52的目标吊舱都有能力出众的摄像器材,新轰炸机和B-2、F22、及F35一样都会都会在蒙皮下安放天线。一些会是雷达天线,收集天空和地面的图像,另一些会监视电磁波,了解敌方的情况。收集的信息将会在飞机上的计算机中处理、与友军交换、共享,形成“作战云”。
这方面来说,新轰的技术得益于F-35十余年的航电技术发展甚多。
战斗指挥
现在的E-3预警机、E-8战场联合监视机都有强大的雷达,在敌方空防系统上如同圣诞树一样显著。新轰则利用其隐身能力潜入,利用其宽频通信能力传送信息,指挥空中和地面力量。
截击
空中截击传统上是由小飞机来完成的,装有强大雷达和长程导弹的轰炸机能够在100英里外攻击敌机 -- 尽管迄今为止此类导弹的使用极为罕见。

周二下午,在国防部长Ash Carter、空军部长Deborah Lee James、和空军参谋长Mark A. Welsh出席发布会上,五角大楼宣布诺格(Northrop Grumman)战胜波音/洛克希德-马丁团队,赢得远程打击轰炸机(LRS-B)合同。

2015年10月27日,美国国防部长阿什顿•卡特、美国空军部长黛博拉•李•詹姆斯和美国空军参谋长韦尔什上将在一场新闻简报会上宣布,授予美国诺斯罗普•格鲁门公司(下称诺格公司)美国空军“远程打击轰炸机”(LRS-B)项目“工程与制造发展”(EMD)合同。詹姆斯部长表示,LRS-B项目对于美国国家安全而言是关键,也是美国空军的最高优先级项目;美国空军需要一直为对的人、对的技术、对的能力和对的训练投资。
LRS-B设计用来取代美国空军老化的轰炸机机队。目前美国空军现役轰炸机机队中,B-52H的平均机龄超过50年,而B-2A的平均机龄也超过17年。LRS-B是远程、高生存力的轰炸机,能够突破未来的“反介入/区域拒止”环境并在其中作战。
该机核常兼备,将赋予美国空军在任何时间,从美国出发对全球任何目标实施打击的战略敏捷性。该机设计上采用开放式架构,允许通过集成新技术来回应未来威胁,并为该机在寿命周期过程中实施竞争性升级改造提供了机会。
EMD阶段合同为成本补偿型合同,包含成本和绩效激励——如果承包商未能做到控制费用和按节点推进项目,这一激励将使其只能获得最低的利润。按照2010年美元值,EMD阶段的费用独立测算结果为214亿美元。合同的第二部分包括采购首批5个生产批次飞机的选择权,包含21架生产型机,而美国空军一共计划采购100架LRS-B。
根据已获得批准的要求,2010年这一计划提出时,该机的单位采购成本要求不高于5.5亿美元(如果按计划采购100架生产型机)。根据独立核计,授予合同中飞机单价按2010的美元值相当于5.11亿美元。

LRS-B: Why Northrop Grumman Won Next U.S. Bomber
Aviation Week & Space Technology
Bill Sweetman
Oct 27, 2015
The U.S. Air Force announced Oct. 27 that Northrop Grumman beat a Boeing/Lockheed Martin team in a competition to develop and build 100 of the bombers, which are expected to reach initial operational capability in the mid-2020s. The Pentagon says the next phase of the work, engineering and manufacturing development (EMD), should cost $21.4 billion in 2010 dollars, including the delivery of an unspecified number of test aircraft.
Another $1.9 billion has already been spent on risk reduction, bringing both competing teams through the initial design phase. In 2016 dollars,
the estimated EMD cost is $23.5 billion, the Pentagon says. The B-2 cost $37.2 billion to develop in 2016 dollars.
The Air Force also says that the average procurement unit cost for the Northrop Grumman bomber (which does not have a formal designation yet) will be
$511 million in 2010 dollars, assuming a 100-aircraft buy ($564 million in 2016 dollars). This figure, the result of two independent Pentagon estimates, is lower than the $550 million (2010 dollars) goal that was set in 2011, when then-Defense Secretary Robert Gates approved the start if the program.
Northrop Grumman’s contract includes fixed-price incentive options for the first five batches of low-rate initial production aircraft, comprising 21 bombers. The price for those aircraft (which will be higher than the average) has not been disclosed. Through production, the program has been estimated to represent $80 billion in business.
The LRS-B is expected to be operational in the mid-2020s. The exact date will depend on initial operational capability criteria, such as a certain number of aircraft in service, which are still to be determined by the Air Force’s Global Strike Command.
The stakes for LRS-B were so huge that industry analysts have long predicted that the losing bidder would protest the award. Boeing is no stranger to that tactic. In 2008, the company successfully protested the Air Force’s 2008 award of a contract for refueling tankers to a Northrop-EADS team and ultimately won the contract in a second competition. Boeing and Lockheed Martin said in a joint statement that they were “disappointed by today’s announcement (and) interested in knowing how the competition was scored in terms of price and risk.” The Air Force says it will start debriefing the loser on Friday, and there is a 100-day period in which to lodge a protest.
“The Air Force has made the right decision for our nation’s security,” said Wes Bush, Northrop Grumman president, chairman and CEO. “Our team has the resources in place to execute this important program.”
For the time being, however, the make-up of Northrop Grumman’s team is a secret, as are most attributes of the program. Not even the engine subcontractor is disclosed, although the Air Force said today that
all major subsystems have been selected. Although
most analysts agree it is overwhelmingly likely that the bomber will resemble a smaller cousin of the B-2, a blended wing-body aircraft with two engines and an unrefueled radius of action of around 2,500 nm, no such details have been confirmed.
Details of the selection process also remain highly classified, but it is likely that the winning bid rested on Northrop Grumman's operational experience with wide-band, all-aspect stealth technology on the B-2 bomber and the still-secret RQ-180 intelligence, surveillance and reconnaissance (ISR) unmanned air vehicle.
But the winning formula was most likely not just a question of delivering more stealth or more range. In LRS-B, the winner had to meet a complex set of requirements that stress risk reduction, an open systems architecture, agile management and manufacturing technology.
The LRS-B contest was unique in three particularly important ways. First, the requirement had emerged from the ashes of the previous Next-Generation Bomber program (NGB), canceled in April 2009, with its goals scaled down and schedule stretched out, and unit cost as a key performance parameter (KPP).
Second, rather than funding demonstration programs, the Pentagon supported two teams through preliminary design review (PDR), probably for almost two years, 2013-15.
A third key feature of the LRS-B is that its management has been assigned to the
Air Force’s Rapid Capabilities Office (RCO), which, Air Force acquisition chief William LaPlante said Oct. 21, has “an incredible track record of
delivering eye-watering capabilities—not just one-offs, but things going into production.”
Significantly, LaPlante describes the 80-strong LRS-B project office within the RCO as like the team that produced the Lockheed F-117 stealth fighter 35 years ago: “A small empowered group of warfighters, acquisition people and maintainers.” Although the
RCO’s only acknowledged aerospace platform is the Boeing X-37B spaceplane, its technical focus can be gauged by the fact that a 2012 recruitment notice for its deputy director identified only three mandatory areas of “significant experience . . .
low-observables,
counter low-observables and
electronic warfare.” Like the F-117, the LRS-B is apparently designed to meet its goals with mature subsystems in a new platform.
However, LaPlante added, the RCO team has substantial oversight from the Pentagon, Congress and Government Accountability Office, and the program incorporates red team/blue team exercises to validate it against possible threats.
The LRS-B contest set an average procurement unit cost of $550 million—in fiscal 2010 dollars based on building 100 aircraft—as a KPP. “The risk is that you pick the wrong number. If you have firm requirements and do the analytics, you have a shot at pulling that off,” LaPlante says.
Some of the key technologies in the LRS-B are both secret and mature
. “Not only have some technologies been wind-tunnel-tested, prototyped or flown—some of them have been used operationally,” LaPlante said Oct. 21.
However, LaPlante also emphasized that delays and overruns cannot be eliminated. “Integration is always a risk,” he said, “and we have put together a schedule with the right margins to accommodate delays.”
LRS-B, too, is planned to be upgraded easily and competitively, “with space and weight provision for things we can’t imagine today,” LaPlante said. Open architecture, he said, could allow the Pentagon to procure a new or upgraded subsystem competitively, “provide it to the prime and say, integrate this.” Along with the cost of maintaining the bomber’s low-observable systems, upgrades will account for a large proportion of the bomber’s life-cycle cost—which will be much greater than its procurement bill.
