According to Sukhoi, the Su-35’s OLS-35 infrared sensor can track up to four targets simultaneously at head-n ranges of 50km (27 nautical miles) and tail chase ranges of 90km (49 nautical miles). The system’s precise range depends on the aspect angle and other factors such as atmospheric conditions. The system also incorporates a laser which can precisely measure target ranges at 20km or roughly (11 nautical miles).
The F-35's designers built it to integrate easily with the Navy's targeting system, so the F-35 can find, track, and provide targeting info to missiles fired from ships or even other jets.
"If you had F-35 loitering as close as possible but not in the airspace, with its sensor package is tuned to pick up a ballistic missile's infrared signature," Bronk said, it could function as a "forward part of the warning chain."
This approach would allow the F-35 to stay out of North Korean airspace, which could be seen as an act of war. Instead, the F-35 simply tracks the ballistic missile, and a US Navy destroyer shoots it down.
This development simultaneously vindicates two of the US military's most important developments: The F-35 and the Naval Integrated Fire Control Counterair Network (NIFC-CA).
Essentially, the NIFC-CA revolutionizes naval targeting systems by combining data from a huge variety of sensors to generate targeting data that could be used to defeat incoming threats. 0177七つの海の名無しさん2018/12/23(日) 05:16:43.15ID:LCfD5bX3 Su-57(とその中国のコピー)はロシアの武器商人や中国人がネットで再三優越性を説いているが、ステルス性能はお話にならないとされる
https://www.quora.com/Which-is-better-the-F-35-or-the-Su-57-PAK-FA The F-35's RCS is somewhere between 100 times & 1,000 times smaller than the Sukhoi (F-35 frontal aspect is close to the F-22). The F-35 is thermally stealthier than the Sukhoi & it is stealthier in electromagnetic emissions. It's radar stealth features are specifically optimized for X-band (PAK-FA fire-control) radar remediation & are less effective, but not ineffective against lower frequencies, including the still undeveloped L-band search radar of the PAK-FA. On the other hand the F-35's smaller, but more sophisticated AESA radar, is more flexible than the Sukhoi's & is a vector for the F-35's cyber-warfare tools. It can not only blind the PAK-FA, it can plant a worm in its fire-control system (according to Gen. C. Bogodan). The F-35's DAS/EOTS passive detection & fire-control suite is unparalleled (so far) in silent long-ranged detection & missile guidance. It can out-range the Sukhoi's radar & IR LOD against the F-35 & shoot/guide undetected BVR missiles. BVR combat -- F-35
In the case of WVR combat, the Sukhoi wins -- right? -- maybe not. The F-35 doesn't fight like a conventional fighter. It's remarkable RADAR/DAS/EOTS capabilities are collectively omnidirectional -- it can see in all directions for great distances in real time & target in all directions in real time & shoot missiles in all direction in real time --- silently & without regard to where the F-35 is oriented. The Sukhoi will not be catching the F-35 pilot unaware & he can see & shoot anywhere at all -- or even evade the Sukhoi -- or trap the Sukhoi. He is not even restricted to using his own missiles. He can command-launch & guide missiles carried by other friendly fighters within range of the Sukhoi. It goes on & on. WVR Combat -- who knows, but it's 1916 tactics vs the death star. 0178七つの海の名無しさん2018/12/23(日) 05:18:07.54ID:LCfD5bX3 Russia Basically Just Admitted Its Next-Generation Stealth Fighter Is A Failure https://taskandpurpose.com/su-57-stealth-fighter-failure/
https://en.wikipedia.org/wiki/Lockheed_Martin_F-35_Lightning_II Pratt & Whitney tested higher thrust versions of the F135, partly in response to GE's statements that the F136 is capable of producing more thrust than the 43,000 lbf (190 kN) of early F135s. In testing, the F135 has demonstrated a maximum thrust of over 50,000 lbf (220 kN);[75] making it the most powerful engine ever installed in a fighter aircraft as of 2010.[76] It is much heavier than previous fighter engines; the Heavy Underway Replenishment system needed to transfer the F135 between ships is an unfunded USN requirement.[77] Thermoelectric-powered sensors monitor turbine bearing health.[78] At the end of May 2017 Pratt and Whitney announced the F135 Growth Option 1 had finished testing and was available for production. The upgrade requires the changing of the power module on older engines and can be seamlessly inserted into future production engines at a minimal increase in unit cost and no impact to delivery schedule. The Growth Option 1 offers a improvement of 6–10% thrust across the F-35 flight envelope while also getting a 5–6% fuel burn reduction.[79]
