Today just three countries operate long-range heavy bombers. Russia has 170 or so Bears, Backfires and Blackjacks. America fields 160 swing-wing B-1s, radar-evading B-2s and stalwart B-52s.
Chinas bomber force is smaller with around 130 H-6s. And most of the H-6s, copies of Russias Cold War Tu-16, lack the long range and heavy payload that many of the Russian and American bombers boast.
But thats changing. After years of work, the Chinese air force has reportedly outfitted two regimentstogether possessing around 36 bombers with a new, much more capable K version of the H-6.
The H-6K is Beijings B-52 a far-flying, fuel-efficient heavy bomber combining a simple, time-tested airframe with modern electronics and powerful, precision weaponry. Although to be fair, the B-52 flies much farther with more bombs and missiles.
Still, over the vast Pacific Ocean, where the tyranny of distance prevents most aircraft from operating efficiently, the H-6K could prove to be one of Chinas most important planes in wartime.
But the H-6K could have a big weakness one that actually has little to do with the bomber itself.
Tupolevs forever
The H-6K is a 21st-century version of a Soviet bomber that first flew in April 1952. The Tupolev design bureaus Tu-16 was the Soviet Unions first big, jet-propelled bomber. Powered by two AM-3 turbojets buried in the wing roots, the subsonic Tu-16 could haul up to 10 tons of bombs nuclear or conventional.
With a standard bombload and no aerial refueling, a Tu-16 could fly more than 1,000 miles before needing to turn back.
The Tu-16, which NATO called Badger, proved to be a solid, reliable airplane, much like the United States B-52, which first flew in 1954 and, with lots of upgrades, is still going strong.
Moscow quickly developed different versions of the Tu-16 for reconnaissance, electronic warfare, aerial refueling and to haul cruise missiles for attacks on U.S. Navy aircraft carriers.
Faster and more modern Tu-22Ms and Tu-160s NATO designations Backfire and Blackjack, respectively replaced the Badgers as the Cold War ended. But the Tu-16 soldiered on in China.
China bought the rights to the Tu-16 in the late 1950s. Over the next 60 years, state-owned manufacturer Xian churned out nearly 200 copies of the redesignated H-6.
Like the Soviets, the Chinese modified the basic, four-person H-6 for a wide range of missions. The H-6A was an atomic bomber. The H-6B was a recon plane. The H-6C was a conventional bomber. Theres an H-6U tanker version. The H-6H, M and K models carry cruise missiles.
But until the H-6K first flew in 2007, all of Beijings bombers were still 1950s-vintage Tu-16s in their guts. Swapping old engines and electronics for modern gear, the H-6K represents a huge evolutionary leap over the old Xian bombers.
The H-6K replaces the original AM-3 turbojets which one analyst called thirsty and maintenance intensive by current standards with much more efficient D-30 turbofans. Without aerial refueling, an armed H-6K can cruise 1,900 miles or so before needing to turn around a big improvement over older models.
Even more impressive, an H-6K that refuels in mid-air twice can reportedly range 3,100 miles from base while hauling 12 tons of weapons, including up to six YJ-12 supersonic anti-ship missiles or CJ-20 subsonic land-attack cruise missiles, capable of striking targets 250 and 1,500 miles away, respectively.
Supported by tankers, an H-6K armed with YJ-12s or CJ-20s could venture deep into the Pacific, hunting for American ships or even flying within striking distance of Americas own main bomber outpost in Guam, some 3,000 miles from the Chinese mainland.
That is, if it can slip through air defenses, analyst Hans Kristensen pointed out. But Jon Solomon at Information Dissemination assumed Chinese fighters would accompany the bombers in order to protect them. H-6Ks can be escorted thousands of miles out to sea by J-11s, Solomon wrote.
Targeting dilemma
But its not enough to just safely fly that far. Long-range strikes especially against moving ships at sea require careful planning and precise targeting. The H-6K sports a new nose radome housing a modern air-to-ground radar, which might help guide a YJ-12 but undoubtedly lacks the power to spot targets for a CJ-20.
Instead, the CJ-20 probably requires mission planners to pre-load precise coordinates into the missiles computer prior to launch. The YJ-12 has its own seeker but the bomber needs to lob the missile into the right general area for the munition to have any chance of detecting and hitting a ship.
It is not clear whether China has the capability to collect accurate targeting information and pass it to launch platforms in time for successful strikes in sea areas beyond the first island chain that is, a couple thousand miles from the Chinese coast, the Pentagon explained in its 2013 report on Chinas military.
Targeting, more than the physics of flight and fuel consumption, is likely the current practical limit on the H-6Ks reach, and thus its wartime usefulness to Chinese commanders.
In battle, a long-range bomber is only as good as the intelligence that tells it where to strike. And when it comes to intel for bomber raids, China might not be quite ready to steer its new H-6Ks.
Just wait. According to William Murray from the U.S. Naval War College, it seems reasonable to assume that China has assessed what is necessary and is investing aggressively to satisfy those requirements.

Short legs.
Hence the creation of airfields on artificial islands in The Spratlys.
Yeah, not being an airplane expert by any stretch, that seems very short. Why wouldn’t refueling make it unlimited. Is it because the tankers are limited?
Lubricants eventually run out.
And if they can't figure it out the Democrats in power in America will sell it to them.
Sukhoi,
Thanks for the article and pic. This is another old bird that is being kept around due to having room for improvement. Too bad we didn’t take advantage of the fact that Grumann did the same in planning for the F-14; the F-21 was to be essentially a product improved F-14 with new capabilities. Just like the old F-84 went through various straight and swept wing variants.
Thanks for the ping. I think China is more likely to use ballistic missiles than long-range bombers.
If you veer aside from an American-centric view of strategic air power, the H-6K is just about right for China’s present requirements and current level of infrastructure. Intercontinental capabilities encompass a lot of things other than just bombers. The H-6K gives excellent stand-off anti-ship and land attack capabilities into the Pacific and Indian Oceans.
I know people talk of a U.S. /China war. But wouldn’t that be more likely in defense of Japan? And all they would need is a platform to attack our carriers.
I simply do ot see the Chinese attacking the CONUS with anything other than nukes.
