F-35 saattaa olla kallis, buginen ja myöhässä, mutta mielestäni erityisesti tuo paikaltaan ilmaan pääsevä F-35B -variantti avaisi täysin uusia mahdollisuuksia koneiden sijoittelulle kriisitilanteessa. Mitä mieltä tästä ollaan?

Kannattaa katsoa aina onko samasta aiheesta jo ketjua tai useampaa olemassa ennen kuin avaa uuden, näin vältymme ketjujen määrän räjähtämiseltä. Tervetuloa foorumille kuitenkin!

F-35 A CPFH laskenut merkittävästi. Se on silti reilu tuplat F-16:n lukuun nähden.

Ei nyt varsinaisesti liity aiheeseen mutta koska tästä on tässäkin säikeessä keskusteltu niin mainittakoon että Kanadan uusi Liberaali-hallitus on nyt julkaissut ensimmäisen budjettinsa (yli 100 miljardia CAD alijäämäinen vaalikauden ajan) ja puolustusvoimien hankinnat tullaan lykkäämään hamaan tulevaisuuteen, niin hävittäjäkoneiden kuin laivojen ja ajoneuvojenkin osalta.

U.S. F-35 chief expects savings after Pratt's B-21 bomber win
The selection of Pratt & Whitney to build the engines for the new Northrop Grumman Corp (NOC.N) B-21 bomber should help Pratt lower the cost of its F135 engines that power the Lockheed Martin Corp (LMT.N) F-35 fighter jet, a top Air Force general said Thursday.
Lieutenant General Chris Bogdan, who runs the $391 billion F-35 program, told reporters that lessons learned from the F135 engine program, any commonality between the engines, and greater engine production could help drive down costs on both programs.
"I would expect that Pratt’s prices on the F135 ought to come down as a result of the work they’re going to be doing on the long-range strike (bomber)," he said after speaking at an event hosted by U.S. defense consultant Jim McAleese.
The Air Force last week named Pratt, a unit of United Technologies Corp (UTX.N), as the enginemaker for the new bomber, but gave no details about the actual engines.
Bogdan said the bomber decision could lead to an increase in F135 engine cores, which could lead to price reductions later.
"There's spillover things that happen if you have two engines that are common," Bogdan said. "There's another source of investment to improve engine manufacturing now."
He said he knew little about the B-21 bomber program, which remains classified, and did not explicitly confirm that F135 engine cores would be used for the new bomber.
Pratt spokesman Matthew Bates declined comment when asked if the the new bomber engine would use F135 engine cores.
He said Pratt had lowered the cost of the F135 engines in every contract with the Pentagon, and remained committed to further reductions.
Bogdan said he hoped to finalize by the end of the month a preliminary agreement with Pratt for 167 F135 engines, under two contracts valued at more than $3 billion combined. Bogdan last month said the cost of those engines would drop by 3 percent to 4 percent in each of the contracts.
He said the program also hoped to reach agreement in principle with Lockheed for a ninth batch of F-35 jets by the end of March, and a 10th batch of jets about a month later. The airframe deals are worth around $16 billion combined, he said.
Bogdan said the F-35 program was continuing to drive down costs, but software challenges with the F-35's automated logistics system meant the Air Force could miss its Aug. 1 target date for an initial combat capability by 45 to 60 days.

"Michael Gilmore, the Pentagon's chief weapons tester, said the program would not be ready for operational testing until mid-2018, a year later than expected"
http://www.newsfultoncounty.com/wor...ter-program-delayed-due-to-software-shortfall
The senior official told lawmakers that “mission system stability including the radar” is still a significant problem as well as fusion of information from sensors on the same aircraft or among different aircraft still continues to be a problem.
“There are shortfalls in electronic warfare, electronic attack, shortfalls in the performance of distributed aperture system and other issues that are classified,” he added.

"The latest software delivered last month “was so unstable that productive flight testing could not be accomplished” so “the extent to which the significant outstanding deficiencies are being addressed thus far is still to be determined,” Gilmore said."

Miten ihmeessä kone joka on jo palveluskäytössä ei ehtisi? Jotkut muut potentiaaliset kilpailijat kun eivät ole lentäneet edes vielä ensilentoaan...

Sama konsepti kuin Gripenillä.
Tuo parantaa kykyä havaita kohteet ja trianguloida niiden sijainnit passiivisesti sensorifuusiolla.

Voi ehkä hyvin ehtiäkin, jos sorvia pyöritetään ahkerasti. Ja toivotaan myös niin että ehtii mukaan kilpailuun. Mutta onko kone nyt oikeasti palveluskäytössä siinä tarkoituksessa, mihin se on hankittu? Vai onko se vielä keskeneräisenä ikään kuin "palveluskäytössä"? No, semantiikkaa tämä toki vain on...
Niistä muista tuossa tarkoitetaan todennäköisesti erityisesti Gripen E/F -konetta. Sitä on lupailtu kiitoradan päähän kesän korvalla. Saa nähdä, aika näyttää. Toivotaan, että sekin ehtii mukaan kilpailuun. Kaksin aina kaunihimpi?

Sanotaan niin, että mikäli se on "palveluskäytössä", niin hyvin monen maan ilmavoimat ovat hyvin isoissa ongelmissa.

Palveluskäytössä on merijalkaväen bertta versio, tarkoittaa kai lähinnä sitä että pystyy tekemään samat temput kuin harrier jonka tilalle tulossa.

Tehtaalta ulos rullanneiden salamien määrä lähentelee kahtasataa siinä vaiheessa kun ensimmäinen ruotsin kotka on kiitotien päässä. Kannattaa muistaa että tämä jsf projekti on ollut poikkeuksellisen läpinänäkyvä. Se että esim pakfa tai gripen ng projektien ongelmista ei blogeissa kirjoitella, ei tarkoita sitä etteikö niitä ongelmia voi olla

Tottakai, varmasti jokaisessa on. Mutta montako youtube videota olet nähnyt joissa VKS:n kenraali tekee projektin ongelmista\ korjausaikataulusta tiliä duumalle

Toimiiko naapuri kuin jenkkilä taikka länsimaat?
Ei kukaan ole väittänyt niin olevan. Lue esim PAKFA ketjua läpi, niin selviää millaisia ongelmia siellä on ollut, mutta siitäkin huolimatta ei "transparency" tee ohjelmasta parempaa.
