Dutch F-16 nearly shoots down … itself

I didn’t think this was even remotely a possibility:

The Netherlands’ Defense Safety Inspection Agency (Inspectie Veiligheid Defensie) is investigating an incident during a January military exercise in which a Dutch Air Force F-16 was damaged by live fire from a 20-millimeter cannon — its own 20-millimeter cannon. At least one round fired from the aircraft’s M61A1 Vulcan Gatling gun struck the aircraft as it fired at targets on the Dutch military’s Vliehors range on the island of Vlieland, according to a report from the Netherlands’ NOS news service.

Two F-16s were conducting firing exercises on January 21. It appears that the damaged aircraft actually caught up with the 20mm rounds it fired as it pulled out of its firing run. At least one of them struck the side of the F-16’s fuselage, and parts of a round were ingested by the aircraft’s engine. The F-16’s pilot managed to land the aircraft safely at Leeuwarden Air Base.

The incident reflects why guns on a high-performance jet are perhaps a less than ideal weapon. The Vulcan is capable of firing over 6,000 shots per minute, but its magazine carries only 511 rounds — just enough for five seconds of fury. The rounds have a muzzle velocity of 3,450 feet per second (1050 meters per second). That is speed boosted initially by the aircraft itself, but atmospheric drag slows the shells down eventually. And if a pilot accelerates and maneuvers in the wrong way after firing the cannon, the aircraft could be unexpectedly reunited with its recently departed rounds.

F-35 delays mean extended life for the F-16

Filed under: Military, Technology, USA — Tags: , , , — Nicholas @ 08:14

Strategy Page looks at the F-16, the “cheap and cheerful” alternative for many countries who are watching and waiting as the F-35 program staggers on.

Many air forces are finding that it’s more cost-effective to upgrade via new electronics and missiles and, as needed, refurbishing engines and airframes on elderly existing fighters, rather than buying new aircraft. This is especially the case if the new electronics enable the use of smart bombs. One of the more frequently upgraded older fighters is the American F-16. Even the U.S. Air Force, the first and still largest user of F-16s is doing this with some of its F-16s.

The U.S. Air Force is currently refurbishing several hundred of its 22 ton F-16 fighters, because their replacement, the 31 ton F-35 is not arriving in time. This is the same reason for many nations to upgrade their F-16s. Some of these nations are holding off on ordering F-35s (or cancelling existing orders), either because of the high price or doubts about how good it will be. Aircraft manufacturing and maintenance companies see a huge market for such upgrades. Half or more of the 3,000 F-16s currently in service could be refurbished and upgraded to one degree or another. That’s over $25 billion in business over the next decade or so.

The F-35 began development in the 1990s and was supposed to enter service in 2011. That has since slipped to 2017, or the end of the decade, depending on who you believe. Whichever date proves accurate, many F-16 users have a problem. Their F-16s are old, and by 2016 many will be too old to operate. Some other nations have even older F-16s in service.

[. . .]

Although the F-35 is designed to replace the F-16, many current users will probably keep their F-16s in service for a decade or more. The F-16 gets the job done, reliably and inexpensively. Why pay more for new F-35s if your potential enemies can be deterred with F-16s. This becomes even more likely as the F-35 is delayed again and again. Finally, the upgrade is a lot cheaper, costing less than $20 million, compared to over $100 million for a new F-35. If your potential enemies aren’t upgrading to something like that, a refurbed F-16 will do.

The Philippines seek some cheap aircraft

Filed under: Asia, China, Military, Pacific, USA — Tags: , , , — Nicholas @ 09:14

Strategy Page, on the Philippines’ financial and strategic problems:

The Philippines is asking the U.S. for some used F-16 jet fighters. The Philippines is broke, so the proposed deal is for free F-16s, with the Philippines paying for any upgrades or modifications needed for service in the Philippines Air Force. Normally, the Philippines has no practical need for a jet fighter force. But this has changed because of possible clashes with China, the Filipinos are being practical. China is claiming Filipino territorial waters, including places where the Philippines authorized drilling for oil and gas. The Philippines could never afford to buy, or even just maintain warplanes sufficient to deal with a Chinese air threat. The Philippines depends on its friendship with the United States for protection. American warplanes provide better protection than any jet fighters the Philippines could put in the air. But the Philippines would like a dozen or so F-16s just so they can chase away Chinese warplanes that increasingly fly into Filipino air space.

Six years ago, the Philippines removed from service its eight F-5 fighters. These 1960s era aircraft were not much of a match for more recent warplanes, and were expensive to maintain. In the meantime, the Philippines has been using armed trainer aircraft for strikes against Moslem and communist rebels.

US Air Force to upgrade F-16 to fill the gap until the F-35 comes into service

Filed under: Military, Technology, USA — Tags: , , , — Nicholas @ 08:41

The delays in the production of the F-35 are forcing the USAF to extend the service life of hundreds of aging F-16 aircraft:

The U.S. Air Force will refurbish several hundred of its 22 ton F-16 fighters, because their replacement, the 31 ton F-35 is not arriving in time. The F-35 began development in the 1990s and was supposed to enter service in 2011. That has since slipped to 2017, or the end of the decade, depending on who you believe. Whichever date proves accurate, the air force has a problem. Its F-16s are old, and by 2016 many will be too old to operate. The average age of existing F-16s is over 20 years, and the average aircraft has over 5,000 flight hours on it. Two years ago, the first Block 40 F-16 passed 7,000 hours. Three years ago, the first of the earliest models (a Block 25) F-16 passed 7,000 hours.

Depending on how late the F-35 is, the air force will refurbish 300-600 Block 40 and 50 aircraft. The work will concentrate on extending the life of the airframe, plus some electronics upgrades. The air force does this sort of thing frequently to all aircraft models. It’s called SLEP (Service Life Extension Program), and this one is special only because it concentrates on very old aircraft and is intended to keep these birds viable for another 5-10 years.

The F-16C was originally designed for a service life of 4,000 hours in the air. But advances in engineering, materials and maintenance techniques have extended that to over 8,000 hours. Because of the wars in Iraq and Afghanistan, F-16s sent to these areas will fly over a thousand hours a year more than what they would fly in peacetime. The current planned SLEP will extend F-16C flight hours to 10,000 (10K) or more.

“RAF’s new superfighter was thrashed in the very type of combat it is supposed to be best at by a 1970s-era plane”

Filed under: Asia, Britain, Middle East, Military, Technology — Tags: , , , — Nicholas @ 07:24

Lewis Page talks about claims from a Pakistani Air Force fighter pilot that their F-16s had “shot down” Royal Air Force Typhoons in three separate air training exercises in Turkey.

The RAF Typhoon, formerly known as the Eurofighter, should nonetheless have been vastly superior in air-to-air combat whether BVR or close in within visual range (WVR). The cripplingly expensive, long-delayed Eurofighter was specifically designed to address the defects of its predecessor the Tornado F3 — famously almost useless in close-in, dogfighting-style air combat. The Typhoon was meant to see off such deadly in-close threats as Soviet “Fulcrums” and “Flankers” using short-range missiles fired using helmet-mounted sight systems: such planes were thought well able to beat not just Tornados but F-16s in close fighting, and this expectation was borne out after the Cold War when the Luftwaffe inherited some from the East German air force and tried them out in exercises.

Thus it is that huge emphasis was placed on manoeuvring capability and dogfighting in the design of the Eurofighter. The expensive Euro-jet was initially designed, in fact, as a pure fighter with no ground attack options at all — bomber capability has had to be retrofitted subsequently at still more expense. Despite lacking various modern technologies such as Stealth and thrust-vectoring the resulting Typhoon is generally touted as being one of the best air-to-air combat planes in the world right now. Certainly it is meant to be good in close fighting: it is armed with the Advanced Short Range Air to Air Missile (ASRAAM) which as its name suggests is intended for the close WVR fight.

Perhaps the account above is simply a lie, or anyway a bit of a fighter pilot tall story. But the pilot quoted will be easily identifiable inside his community if not to the outside world, and he could expect a lot of flak for telling a lie on such a matter in public. It seems likelier that the story is the truth as he perceived it: that the RAF’s new superfighter was thrashed in the very type of combat it is supposed to be best at by a 1970s-era plane, albeit much modernised.

No more manned fighters?

Filed under: Military, Technology, USA — Tags: , , , , , , , — Nicholas @ 12:24

As I said the last time this topic came up, “This is not a repost from 1957”. We may actually be looking at the last generation of manned fighters, if this update from Strategy Page is true:

On February 4th, the U.S. Navy X-47B UCAV (unmanned combat air vehicle) made its first flight. It was three years ago that the navy rolled out its first combat UAV; the 15 ton X-47B. This pilotless aircraft has a wingspan of 20 meters/62 feet (whose outer 5 meter/15 foot portions fold up to save space on the carrier). It carries a two ton payload and will be able to stay in the air for twelve hours. The U.S. is far ahead of other nations in UCAV development, and this is energizing activity in Russia, Europe and China to develop similar aircraft.

[. . .]

All of these aircraft are stealthy and can operate completely on their own (including landing and takeoff, under software control). The UCAVs would be used for dangerous missions, like destroying enemy air defenses, and reconnaissance. Even air force commanders are eager to turn over SEAD (Suppression of Enemy Air Defenses) missions to UAVs. SEAD is the most dangerous mission for combat pilots. But until quite recently, all these projects had either been cancelled, or were headed in that direction.

Now, the U.S. Department of Defense wants the new UAV combat aircraft in service by the end of the decade, some twenty years ahead of a schedule that was planned in the 1990s. The F-35 is expected to cease production in 2034, more than a decade after the first combat UAVs, that can match F-35 performance, enters service.

Unable to buy new aircraft designs (because they are too expensive, or simply take too long to get into service), and facing the prospect of unmanned aircraft (UAVs) displacing more and more manned ones, the American military is spending a growing chunk of its budgets on upgrading and refurbishing the combat aircraft they already have. This was not a deliberate, long term plan, but simply a reaction to shortages of new aircraft. A lot of the new electronics and weapons involved in these upgrades can also equip UAV designs still in development, so such efforts are a double win.

More and more, it looks like the new 36 ton F-22 and 27 ton F-35 are the end of the road for manned fighter-bombers. Not just because the F-22 and F-35 cost so much to develop, but because so much new tech has arrived on the scene that it simply makes more military, and economic, sense to go with unmanned aircraft. Meanwhile, the existing F-15s, F-16s, F-18s, A-10s and all American heavy bombers are being equipped with new targeting pods and combat Internet connections, along with new radars and all sorts of electronics. Older aircraft are having worn out structural components rebuilt or replaced. This buys time until the unmanned aircraft are ready. F-35s will also fill the gap, which may be a very small one.

Usual caveats apply of course, and you could do worse than reading the comment thread on that original post for some of the caveats spelled out.

Training to fight lower-tech aircraft in the air

Filed under: Military, USA — Tags: , , , , — Nicholas @ 09:41

Strategy Page rounds up information on US Navy efforts to keep their air-to-air combat skills fresh:

The U.S. Navy has refurbished a surplus U.S. Air Force National Guard F-16 flight simulator to help keep its F-16 pilots in shape for using F-16s to train navy pilots (in F-18s) how to best deal with Chinese, and other potential enemy, pilots. The navy uses F-16s because these aircraft are best able to replicate the performance of likely high end enemy fighters. That’s because Russia and China have used the F-16 as the model for most of their latest fighters (the Russian MiG-29 and Chinese J-10). The navy bought 26 of a special model (F-16N) of the aircraft in the late 1980s. But in the 1990s, the navy retired its F-16Ns, because of metal fatigue, and had to wait nearly a decade before it got sixteen more. The refurbished simulator had its cockpit modified to reflect the one the navy F-16s use.

The navy also uses F-5s to simulate lower performance enemy fighters. Two years ago, the navy completed a six year effort to buy and modify 44 F-5E fighters from Switzerland. The U.S. uses F-5s, a 12 ton fighter roughly similar to the MiG-21. The F-5 is normally armed with two 20mm cannon, and three tons of missiles and bombs. The U.S. Navy modified and refurbished the Swiss F-5s so their performance better matched that of Russian or Chinese aircraft.

It may sound odd to have older equipment still in service, but they are very useful for training purposes. Both the air force and the army will perform better if they’ve trained against the kind of equipment and tactics used by likely opponents, and it’s unlikely that you can arrange a “friendly” wargame exercise against a force you may be fighting for real in the near future.

The other thing is that the troops playing the “other side” in wargame exercises tend to have a lot more fun doing so . . .

Costs continue to rise for F-35B aircraft

Filed under: Economics, Europe, Military, USA — Tags: , , , , , — Nicholas @ 08:47

Strategy Page has more on the increasing spendiness of the F-35 program, especially the part the Navy is most concerned about:

Denmark has decided to wait, until 2014, to decide what to replace its elderly F-16 fleet with. Meanwhile, 18 of the F-16s will be retired. But the other 30 will be refurbished so that they can continue to operate for the rest of the decade. Denmark had wanted to replace the F-16s with F-35s. But the F-35s keeps getting delayed (now more than two years behind schedule), and is becoming more expensive (nearly a hundred percent over budget). The Danish F-35 buy is no longer a sure thing. The delays have lots of users concerned. The U.S. Navy has been nervously watching as the costs of the new F-35C and F-35B carrier aircraft versions go up.

It comes down to this. Currently, it costs the navy, on average, $19,000 an hour to operate its AV-8 vertical takeoff and F-18C fighter aircraft. It costs 63 percent more to operate the F-35C (which will replace the F-18C) and the F-35B (which will replace the AV-8). These costs include buying the aircraft, training and maintaining the pilots, the aircraft and purchasing expendable items (fuel, spare parts, munitions.) Like the F-22, which recently had production capped at less than 200 aircraft, the capabilities, as superior as they were, did not justify the much higher costs. The F-35, at least for the navy, is headed in the same direction. The navy can go ahead with the more recent F-18E, and keep refurbishing, or even building, the AV-8. Politics, and lobbying by the F-35 manufacturer, will probably keep the F-35 headed for fleet service, no matter what the cost.

Another ally watching the F-35B costs rise with trepidation is the Royal Navy, whose aircraft carriers are not able to handle conventional aircraft (even the two large carriers under construction won’t have catapults for launching non-STOL planes). Earlier posts on the Royal Navy’s carrier worries here and here.
