The most recent reports from China suggest a third new build variant is in test, usually labelled the 'H-6K'. This subtype is claimed to have a solid nose not unlike the H-6U, six wing pylons for cruise missiles, one centreline pylon, and a bomb bay fuel tank. There is speculation that it may use a new turbofan engine. Given the baseline payload of a pair of Krakens or KD-63 on the H-6D/H, it is likely that the 'H-6K' will be limited to weapons in the 2,000 lb class, such as ASCMs, rather than longer ranging LACMs.

Re: H-6 bomber thread

reports of first flight of H-6K on January 5th. There is actually report of another successful first flight for XAC. Not sure if this is the one for H-6K or the other one.
apparently, this one says 20000 XAC employee waited 13 years for this moment and the first flight is successful. It's hard to comprehend that 13 years is required to modify H-6 to use new engines and such. Maybe there is another bomber coming out?
2007年1月5日14时55分,随着某重点型号飞机腾空而起,这一刻成为载入西飞、乃至中国飞机发展史册的一个永恒的瞬间。2万多西飞人13年的期盼凝聚在这一刻:某重点型号飞机首飞圆满成功!
  掌声与鲜花、笑语与自豪装点着冬日暖阳照耀下的机场。中央军委首长、空军装备部首长、国防科工委领导、陕西省委副秘书长、西安市副市长、中国一航、中航二集团等单位领导与数百名西飞参研人员共同见证了这激动的时刻。
  14时50分,随着首飞仪式主持人、中国一航副总经理李玉海宣布:“首飞开始!”。银灰色的某重点型号自西向东,穿过观礼台,缓缓滑向跑道。随着优美的滑跑,在一阵轰鸣声中,飞机昂首直刺蓝天,在观礼台前腾空而起!顿时,全场掌声雷动。人们仰首目送着飞机矫健的身姿融入在碧空之中……
15时06分,飞机再次进入人们的视线,打出的一串彩色信号弹在空中散开、飞舞,飞机开始通场飞行,如潮的掌声再次响起,激动、自豪洋溢在人们的脸上。
  15时15分,飞机打开两个白色阻力伞,平稳着陆,减速滑行。经过蓝天洗礼后格外雄壮的飞机,稳稳停在观礼台前方。至此,某重点型号首飞圆满成功!现场的领导兴致勃勃登上英姿勃发的某重点型号飞机,与机组人员亲切握手、合影留念。
  首飞仪式后,西飞集团公司总裁高大成汇报了某重点型号研制过程和体会。中央军委首长、国防科工委领导在发言中充分肯定了某重点型号研制的重大意义与前期的工作情况,对后续工作提出了希望与要求。一航副总经理李玉海代表西飞以及各参研单位做了表态发言。
the other report of a new plane making maiden flight, this one could also be on H-6K. This happened on December 16th.
12月16日上午,西飞研制的某型号飞机顺利实现首飞,如期完成了全年飞机研制的又一关键节点目标。
上午9时36分,碧空如洗,阎良机场沐浴在一片暖阳之下。某重点型号昂首静立在跑道的一端。随着指令的发出,飞机立即点火、低速通场滑跑,震耳欲聋的发动机轰鸣声在机场上空响起。
9时45分,飞机回到起点,调头对准跑道。随即,滑跑、加速、昂首升空!飞机如一只展翅的雄鹰稳健地升起,在人们注视的目光中,渐渐地消失在远方的天空中……
9 时54分,飞机渐渐地由远及近,低空通场飞行,在飞越机场上空时,突然射出一组信号弹。红色的信号弹划出一道道白色的烟雾,在蓝色天空的映衬下,显得格外耀眼。观礼台上,西飞集团公司总裁高大成和中国一航产品部有关领导,以及现场所有的人们为飞机精彩的表演发出热烈的掌声。
10时03分,飞机平稳降落,两只白色的减速伞迅速张开。人们再次爆发出热烈的掌声。
10时10分,完成首飞的某型号飞机滑入辅道,银色的机身在阳光下发出耀眼的光芒,显得英姿勃发。当机组人员刚一走下飞机,高大成总裁上前将一束鲜花送到飞行员手中,并与他们一一握手,致以亲切的问候。现场领导与机组人员在飞机前合影留念。
yeah, compared to previous H-6, the shape of the intake does seem to have changed, it looks like it got stretched a little vertically and compressed a little horizontally. Also, it's nice to see that chin radar getting removed and housed in the nose instead. Also, it seems to be that the missiles looks the most like YJ-62 (maybe an air-launched type?). 6x1350 = 8.1 tonne of payload on the wings.

also, the changing of engine on H-6 was discussed in 2005 on this thread, so I got some figures here.

The bench testing of Burlak D-30KP engine revealed its thrust performance in full conformance with the specifications announced: 13 tonnes at ambient temperatures up to + 30 degrees C - same as its test-bench specific fuel consumption at full throttle. After fine-tuning, its performance boosted to capacity, the engine "is virtually ready to go into production".

"We have obtained a result that is better than promising; for a fine-tuned engine, it is an excellent result, pure and simple, matching the performance predicted," says Alexander Elkes, chief designer of Burlak D-30KP engine. "The next phase in the programme should see the entire testing cycle completed, requiring 10 engines to be produced. This year, NPO Saturn's plans provide for two engines to be assembled, one of these to be used for emission tests, with TsIAM expected to be involved in them.”

The commercial department having requested that Burlak D-30KP engines be put into service on the IL-76 family aircraft ASAP, contracts are being drawn up to buy an IL-76TD aeroplane, to be reengineered as a flying laboratory, with contracts being drafted in parallel to design and manufacture an engine nacelle, for the engine to be supplied to the customer packaged with it, in line with international practices for the supply of aircraft engines.

Burlak D-30KP is a sound commercial project. "In terms of value for money, this engine is a hands-down winner," the developers say confidently. As of today, NPO Saturn has invested 150+ mln of its own money into the engine development effort, but for the programme to be completed ahead of time, the state's assistance is of the essence.

The engine will be installed on the Il-76 aircraft in operation in Russia and Air Forces of the countries outside the CIS. Once the aircraft has received a souped-up powerplant, its performance will be boosted across the board, to meet the modern-day requirements, viz.:

- fuel efficiency will go up 11% when cruising;

- the aircraft operation geography will be expanded (thrust increased up to 13000 kg sec, and sustained up to a temperature of +30 degrees C);

- the environmental performance will meet long-range ICAO targets);

- the aircraft’s flight-performance will improve.

OAO Nauchno-Proizvodstvennoye Ob"yedineniye Saturn is a leading engine-building corporation specializing in developing, manufacturing and servicing gas-turbine engines for military and civil aviation, Naval ships, energy-generating and gas-pumping installations.

Re: H-6 bomber thread

wait, are you saying that current h-6 are using wp-8 engines?
yes, is there something wrong? I thought huitong also mentionned that in his summary. According to the guy posting in the thread, China did consider replacing 2 WP-8 with 4 WS-9, but there was too much changes required. Whereas with D-30KP, you still use 2 engines and the dimensions are relatively close, so that's why it was chosen, btw, interesting enough, this was already done in June of 2005.

Re: H-6 bomber thread

Im sorry, i was an idiot then. I completely misunderstood the engine situation. if old engine was ws8 then d-30 is a definite improvement in every way. Cool. :)

Re: H-6 bomber thread

btw, it's interesting that I bumped into this today. It mentionned not H-6K but H-6X. fits the description of H-6M on huitong's site.

it basically says that it carries 4 ASM and was used from 01 to 04 to replace old H-6. It carries YJ-83, which has a range of 250 km and terminal speed of mach1.4

Re: H-6 bomber thread

is it me or do the missiles on that thing look nothing like yj-8 series? I fail to see the midbody wings, plus their overall size seems slightly off.
could it be the clone of Kh-55SM Kent which china has illegally acquired from Ukraine?

Re: H-6 bomber thread

I am thinking they increased the thrust and decreased fuel consumption by replacing the engines, probably did some minor lightening of the airframe by redesigning a few parts, and that allows for an increase in MTOW, meaning more fuel and ordinance can be carried. So yes, I think there is a good chance that the range on the H-6K has been increased.

And those missiles? Probably a new anti-shipping missile, or a new stand-off land attack cruise missile, judging from the shape (I don't see no mid-body fins, maybe they are folded in until launch?).

Re: H-6 bomber thread

another new photo on H-6K, and it seems to have a solid nose cone with a long refueling probe sticking out.
