In August 2001, the AH-64D was selected by the Japanese Ground Self-Defence Force with a requirement for 55 helicopters. The Apache for Japan is designated AH-64DJP and is armed with Stinger air-to-air missiles. Boeing says it anticipates Japan will order more Fuji Heavy Industry (FHI) assembled AH-64D Apache helicopters despite zero funding allocations for the programme from Tokyo for the past two financial years. The current Japanese mid-term forward defence programme, which ends this year, supported orders for just seven aircraft out of a proposed 64 aircraft fleet. The next mid term defence programme is due for release in September alongside a new annual Defence white paper detailing spending plans for 2010. Boeing says that “feedback from FHI indicates that it is optimistic about future procurement”. Japan uses a year by year financial approvals system for all military hardware allocations. Its existing AH-64D build programme saw two aircraft ordered in FY2005, one in FY2006 and one in FY2007. That pattern effectively means full fleet development would take more than two decades. The 2008 Japanese annual defence white paper, released last July, confirmed that only 4 out of the seven proposed aircraft had been delivered with those aircraft relegated for use in special force and counter insurgency operations. FHI handed over the first Japanese AH-64D to the self defence air force in March 2006. Boeing confirmed at the 2008 Singapore airshow that Japan was concerned that a transition by the US Army from Boeing AH-64D Block II to Block III aircraft was likely to result in its self defence forces fielding a mixed configuration fleet. Boeing has proposed sustainment of the Block II configuration to enable an expansion of the Japanese fleet but declines to comment on whether that offer has been accepted. in a written statement provided to Rotorhub 29 April the company said it “stands ready to support all of its customers in the production of the Apache helicopter”. 综合日本《新闻周刊》等媒体报道,近期,日本自卫队对外展示了国产型AH-64DJ型“长弓阿帕奇”武装直升机。AH-64DJ是由美国波音公司授权日本生产的AH-64D直升机的改进型,其生产成本远高于美军的AH-64D。如果按成本价来算,每架AH-64DJ的单价达2亿多美元,是全球最昂贵的武直。 日本“阿帕奇”项目一团糟 日本国产型AH-64DJ于2006年2月成功完成首飞。但目前来看,日本自卫队引入AH-64DJ的项目已陷入了一团糟。 日本陆上自卫队原打算配备62架AH-64DJ。但现实是,由于国防费用的削减,日本自卫队每年只买得起数架AH-64DJ,目前AH-64DJ的本土生产装配工作已几乎完全中止,日本陆上自卫队一共仅拥有约13架AH-64DJ。 日本授权制造商富士重工业损失惨重,其之前获得的装配几十架AH-64DJ的合同成了一纸空文。此外,该公司曾花费巨资从美国企业购买了用于生产AH-64DJ的流水线,还白白向美国方面支付了约合3.5亿美元的技术授权费。富士重工业因为订单被取消,最后不得不向日本防卫省索要赔偿以减轻损失。 “最贵武直”前景黯淡 究竟是什么原因让AH-64DJ项目陷入窘境?日本军事专家猜测,其中有3点因素:一,当日本企业在装配生产AH-64DJ时,美国军工企业已经开发出了性能更出色的新版阿帕奇,而美方并未向日本制造商授权制造新版阿帕奇搭载的一些关键设备,这也意味着AH-64DJ在将来很难升级至最新版阿帕奇。这导致日本自卫队一些高官对是否还需要采购”旧款阿帕奇“——AH-64DJ产生了怀疑,他们最后决定中止扩大购买AH-64DJ的计划。 二,日本陆上自卫队在接受首批AH-64DJ后发现,该武直通讯系统所用的无线电频段在国内已被他用,这就影响了AH-64DJ的隐蔽通讯能力。 三,AH-64的引入比预想中的更花钱。日本陆上自卫队目前装备有13架AH-64DJ,若按成本价来算,其单价竟达2.13亿美元(美军AH-64D的单价不超过5000万美元),已接近美国F-22战机(美国参议院拨款委员会主席丹尼尔曾希望以每架2.5亿美元的价格,向日本出口F-22)。如此高昂的价格,使得日本陆上自卫队在2007年一年只装备了1架AH-64DJ。虽然通过大量生产能摊薄AH-64DJ的生产成本,但在自卫队经费遭削减的大环境下,这几乎不可能发生了。 日本军事专家表示,由于AH-64DJ项目面临挑战,陆上自卫队未来或许将大量引进最新款阿帕奇AH-64E,以进口版AH-64E全面替代AH-64DJ。 More about AH-64 helicopter
