Not the first one to go down and won't be last. Definitely better to lose drones like the Reaper.

Looks like the MH 370 report mentions that no one will ever know what happened to it unless there's new evidence.

Sputniks?

Something like that, there abouts. I bet we could make them cheaper today though.

Reapers are about 18-19 million per craft if that is what you are asking.

Now you've got me wondering how much Sputnik costs compared to a modern comms satellite once adjusted for inflation.

An MQ-9 has a 16.9 million dollar fly away cost according to the 2013 budget report.

Which puts it's cost in the neighborhood of my early estimates thanks to inflation on a multi-million dollar item.

Sputnik though has no listed cost that anyone seems to have found. The only thing we could possibly say is that it wasn't cheap.

DARPA wants Aerojet Rocketdyne to help develop and demo a combined cycle engine that will enable aircraft to go from sub-sonice into hyper sonic velocities on craft.

Snippets from the article.

As the U.S. steps up research and development for hypersonic weapons, DARPA has awarded Aerojet Rocketdyne a contract to demonstrate a turbine-based combined cycle (TBCC) engine that could power a reusable high-speed aircraft from takeoff to beyond Mach 5.

The award comes amid reports that Lockheed Martin’s Skunk Works is making progress toward flying an F-22-sized, TBCC-powered flight research vehicle by 2020 as a precursor to the larger SR-72 high-speed aircraft proposed for the late 2020s.

DARPA’s Advanced Full Range Engine (AFRE) program differs from previous hypersonic TBCC development efforts in that it combines an off-the-shelf turbine engine with a dual-mode ramjet/scramjet (DMRJ).

Previous programs required an unproven high-Mach turbojet in an attempt to bridge the gap between the highest speed at which a turbine engine can operate and the lowest speed at which a ramjet can take over. Conventional turbojets can operate up to around Mach 2.5, but ramjets cannot operate effectively much below Mach 3.5.

The technical challenge of AFRE involves extending the operability of the conventional turbine engine up to higher Mach number and the operability of the DMRJ down to lower Mach number to enable mode transition. The engines will share a common inlet and nozzle, with the turbine “cocooned” at high speed and then restarted once the hypersonic vehicle slows down for return to a runway landing.

DARPA documents show AFRE was planned to be based on an available Rolls-Royce F405 Adour small turbofan, possibly fitted with a special afterburner enabling operation to higher Mach number. Aerojet Rocketdyne has previously developed the SXJ61 hydrocarbon-fueled and -cooled scramjet that in 2013 powered the Boeing X-51A Wave Rider demonstrator to a speed exceeding Mach 5.1.

Other technical challenges include thermal management in all propulsion phases; integrated propulsion and transition control; matching mass flows through the different flowpaths; achieving combustion stability in the DMRJ; restarting the turbine engine at high speeds and dynamic pressures; and the ability to scale the TBCC design up to power full-size hypersonic vehicles.

Crossposting from the China thread:

Fake paperwork, poor parts challenge China's aerospace boom

SHANGHAI (Reuters) - Chinese suppliers to U.S. flight control systems maker Moog (MO Ga.N) sold it poorly made parts, faked paperwork and outsourced work to a factory not approved by the company, according to an internal report by U.S. aviation regulators.

In a 9-page report dated Nov. 4, 2016 obtained by Reuters through a freedom of information request, the Federal Aviation Authority (FAA) said 273 affected parts were installed in an unspecified number of Boeing 777 wing spoilers, which help slow a plane when coming in to land.

It did not identify the parts or say when they were installed. The FAA, Boeing (BA.N) and Moog said in the report and in emails to Reuters they posed no safety risk.

According to German media, smoke from fires kicked up by ex-Hurricane Ophelia and then transported by winds from same (along with desert dust) has caused some planes to fill with smoke.

This hurricane season is truly a hydra of Lerna.

The F-35 Rumor Mill Is Spinning After Israel's Counter-strike On Syrian SAM Site.

Did an F-35 get successfully detected, engaged and hit by a Syrian SAM system? Unlikely, but the possibility can't be ruled out. After all, "bird strikes" were used in the Cuban Missile Crisis.

Man I dunno, even by some of it's less than flattering estimates it shouldn't be getting picked up by an export model Sa-5.

And I don't think Israel would be stupid enough to risk one of only seven models it has when it's so untested.

But this is some really suspect timing and that it was a "bird strike".

Estimated IOC for Israeli F-35s should be in December for those currently available.

And given that an Sa-5 has ~217kg of explosives in it I really don't think that anything one connects with is flying home. Not even an A-10.

Krieger: Given even MANPAD sized warheads have downed even A-10's and not much larger SHORAD missiles have blown larger craft out of the sky; the SA-5 is overkill for most of those.

The SA-5 is one of those weapons platforms that almost counts. The article also admits that the claims are quite likely spurious given the sources making the claim in the first place. Add in the abundance of craft that would be far easier to track and detect never mind lock onto and I have serious doubts there is any validity to the rumor mill.

Reminds me of the time someone tried to convince me the Serbians shot down a B-2 (as far as I can tell, they got the B-2 conflated with the very different but also stealthy F-117).

I also recently learned that some Argentinians claim a successful attack on a British aircraft carrier during the Falklands War.

[up]Wait, dince the f-117 get shot down because a radar operator got very lucky and was looking in the right spot when the bay doors on the plane opened, briefly giving it a lockable radar signature?

#16773: Oct 17th 2017 at 11:03:39 PM

No, its because OpSec is not that bright and flew the same route multiple times.

The F-117 is hard to spot by radar, not by eye, especially when you can confirm when it is going to show up with an intercepted communication.....

And so he ambushed it when it flew the route next, and yes, as you said opened the bombay doors.

But it wasnt luck that let them do so.

The F-117 flew the same route, Serbs had spotters in Italy working for them and the Nighthawk is stealthy as a barn with the bomb bay doors open.

That "low frequency" canard has been going since the F-117 was revealed in 1989.

Shaping offers far fewer stealth advantages against low-frequency radar. If the radar wavelength is roughly twice the size of the target, a half-wave resonance effect can still generate a significant return. However, low-frequency radar is limited by lack of available frequencies (many are heavily used by other systems), by lack of accuracy of the diffraction-limited systems given their long wavelengths, and by the radar's size, making it difficult to transport. A long-wave radar may detect a target and roughly locate it, but not provide enough information to identify it, target it with weapons, or even to guide a fighter to it.[35] Noise poses another problem, but that can be efficiently addressed using modern computer technology; Chinese "Nantsin" radar and many older Soviet-made long-range radars have been modified by supporting them with modern computers

Eh, you can give Mr. Magoo an 8 core Iphone 8 but he still can take good pictures.

The problem with low frequency is that it can't see below the wavelength. So an F-35 looks like: an F-16, a learjet, a MIG or a turoprob full of nuns flying to teach orphans how to sing - at the long range detection distances.

Jamming isn't noise, it's defeating Daredevil by blasting KatyPerry at him. A radar being jammed sees only noise because the noise muscles out the weaker return signals from aircraft.

If the propaganda is to be believed HMS Invincible was sunk at least three separate times during the war.
