F35 JSF Actualité

The Lockheed Martin F-35 Lightning II is the most advanced aircraft in the Pentagon's arsenal, but Russia's powerful over-the-horizon Podsolnukh (Sunflower) radar is capable of detecting and tracking the stealth fifth-generation plane or any other fighter jet that was designed to avoid detection, Svobodnaya Pressa reported.
The Podsolnukh short-range over-the-horizon surface-wave radar is developed by Moscow-based OJSC NPK NIIDAR. The Russian Defense Ministry plans to deploy several of these systems in the Arctic, as well as on Russia's southern and western borders.  

The radar is capable of detecting sea surface and air objects at a maximum distance of 500 kilometers (over 310 miles) at different altitudes in line of sight and over the horizon. The Podsolnukh "can simultaneously detect, track and classify up top 300 sea and 100 aerial targets in an automatic mode," the Global Security website detailed
There is an additional advantage that this type of radars brings to the table. "Short-wave stations see stealth fighter jets as clearly as WWII-era aircraft," Svobodnaya Pressa observed, referring to cutting-edge planes that have been created to avoid detection by radars or sonars, like the F-35.
The Podsolnukh has more to offer. The system could be put online in ten days and needs a team of just three people to stay operational, the media outlet explained. It does not need much power, it is easy to operate and it does not have much equipment. The radar stations have to be placed 370 kilometers apart to receive complete coverage. 

Sea- and shore-based OTHR systems are becoming increasingly popular in coastal nations, who want to protect their exclusive economic zones from piracy, smuggling and illegal fishing. They also have military application. The radars could are capable of issuing alerts in case of an invasion or subversive activity.
Three Podsolnukh stations are operational in Russia at the moment. They are located in the Sea of Okhotsk, the Sea of Japan and the Caspian Sea.

Beochien a écrit:On a un truc, assez proche du Sunflower Russe, développé en France !
Le radar Stradivarius, un peu plus typé Maritime et Over the Horizon (200 Nm pour l'instant)
Lequel utilise comme le Russe les ondes de surface.
Même principe , mais pas du tout typé aviation, et encore moins détection stealth.
Par contre l'infrastructure est nettement plus modeste.
Maintenant s'il y a des développements militaires, on n'en sais rien.

Ce qui m'a surpris, c'est que les Russes semblent avoir tiré un parti "aérien" des ondes de surface avec leur Sunflower, voir où ça mène, mais les équipements sont certainement moins importants !

Martin Baker (Hall 4 Stand G110) says that a solution to a safety problem with the F-35 ejection seat is two-thirds of the way through a testing program. Lt. General Chris Bogdan, the F-35 program executive officer, said last week that the proposed fixes will meet all F-35 requirements.

Toujours perplexe sur cette machine qui ne peut probablement pas être qualifié de multirôle

During a recent exercise at Mountain Home Air Force Base, Idaho, F-35 squadrons wanted to practice evading surface-to-air threats. There was just one problem: No one on the ground could track the plane.

“If they never saw us, they couldn’t target us,” said Lt. Col. George Watkins, the commander of the 34th Fighter Squadron at Hill Air Force Base, Utah.

The F-35s resorted to flipping on their transponders, used for FAA identification, so that simulated anti-air weapons could track the planes, Watkins said.

The F-35A Lightning II fifth-generation fighter aircraft was declared ‘combat ready’ by Gen. Hawk Carlisle, the commander of Air Combat Command, Aug 2.

Carlisle lauded the aircraft’s performance, noting that the aircraft had met all key criteria for reaching initial operational capability: Airmen trained, manned and equipped to conduct basic close air support, interdiction and limited suppression/destruction of enemy air defenses in a contested environment with an operational squadron of 12-24 aircraft; the ability to deploy and conduct operational missions using program of record weapons and missions systems; and having all necessary logistics and operational elements in place.
