美國陸軍重新考慮“火力偵察兵”無人機、小型戰術無人機系統
[據英國《飛行國際》2009年12月15日報導]美國陸軍訓練和條例人員已完成了一份新的分析報告,重新考慮對諾•格公司的MQ-8B“火力偵察兵”無人直升機的採購。無人機系統的訓練和條例能力的主管Robert Sova上校稱該分析報告比較了MQ-8B和AAI公司的RQ-7C“陰影”無人機(由固定翼無人機RQ-7B升級),但目前仍然沒有做出決定。
陸軍提議進行MQ-8B項目後僅兩個月,該分析報告就對MQ-8B專案的未來提出了新的疑問。在10月,陸軍提出了一個新計畫取代下馬了的未來戰鬥系統(裝備73個現代化旅級戰鬥組(BCT))。新計畫中的每個旅將裝備IV類無人機系統,在2003年陸軍選擇了MQ-8B。諾•格公司已向陸軍交付了8架MQ-8B,但這些無人機目前仍然停放在諾•格公司密西西比州的Moss Point廠房裏,這些無人機計畫在2013年服役。Robert Sova稱由於MQ-8B的費用問題,陸軍官員對該無人機專案的必要性產生了懷疑。陸軍軍官正考慮對目前的無人機系統採購做幾處改變。例如,陸軍現在承認了對類似波音/ Insitu“掃描鷹”的無人機系統的需求,“掃描鷹”已經裝備了海軍、海軍陸戰隊和特種部隊。無人機系統的專案經理Gregory Gonzalez上校稱“陰影”裝備旅級部隊,手拋式無人機裝備連級和排級部隊,陸軍需要填補上述無人機空白的營級小型戰術無人機。陸軍也已經投資採購拖曳式貨運無人機,在長遠的規劃中計畫將有人貨運飛機和通用直升機轉換為可選有人駕駛飛機。(中國航空工業發展研究中心 陳宣友)

US Army rethinks Fire Scout, STUAS and unmanned cargo aircraft

US Army training and doctrine staff have completed a new analysis that reconsiders the service's commitment to the Northrop Grumman MQ-8B Fire Scout unmanned helicopter.
The analysis compares the MQ-8B with the AAI RQ-7C Shadow, a proposed upgrade of the fixed-wing RQ-7B, says Col Robert Sova, training and doctrine capabilities manager for unmanned aircraft systems.
The completed analysis recommends a course of action, but the results remain undisclosed, Sova told the UAS Symposium of the Army Aviation Association of America (Quad-A) on 10 December.
"There has not been a decision yet in terms of the outcome," Sova said.
The analysis raises fresh doubts about the Fire Scout programme's future only two months after the army proposed to expand the programme.
In October, the army released a new plan to replace the cancelled Future Combat Systems with 73 modernised brigade combat teams (BCT). Each brigade under the new plan would be equipped with the Class IV UAS, which the army selected Northrop in 2003 to deliver the MQ-8B.
Northrop has delivered eight MQ-8Bs to the army, but they remain parked at Northrop's facility in Moss Point, Mississippi. The aircraft are scheduled to enter service in 2013.
Sova says army officials have questioned the need for the Fire Scout programme given its expense: "Because these things are expensive, we need a comparison between something you already have. With this capability that was a part of the FCS Class IV BCT."
Army officials are considering making several changes to its existing acquisitions for UAS. For example, the army now acknowledges a need for a UAS similar to the Boeing/Insitu Scan Eagle, which has already been deployed by the navy, marines and special operations.
With Shadows operated at the brigade level and hand-launched systems pushed down to companies and platoons, the small tactical UAS would fill a gap at the battalion level, says Col Gregory Gonzalez, UAS programme manager.
The army also has laid out a strategy for acquiring the ability to haul cargo without putting flightcrews at risk. Army officials have a far-term plan to convert manned cargo and utility helicopters to optionally manned systems.
"Not only will we see it," Sova says. "I think we should do it because we're leveraging the investment we've already made." |
