F-35 Lightning II

Tällainen siistimpi kuva, josta laskin yhteensä n. 120 F-35:a. Eli tuolta näyttää karkeasti yhdessä kuvassa pumppu, joka olisi noin tuplasti meidän tulevaa fleetiä isompi. Tai suurin piirtein tuolta näyttäisi koko Britannian alun perin kaavailema 138 F-35:n pumppu taivaalla.

Switzerland to receive most F-35s from Italian plant
24 Mar 2022 Gareth Jennings

"Switzerland is to receive the bulk of its Lockheed Martin F-35 Lightning II Joint Strike Fighter (JSF) aircraft from the Italian production plant in Cameri, the Federal Department of Defence, Civil Protection, and Sport (VBS) said on 24 March.

The VBS announced that most of its F-35A aircraft will come from the final assembly and checkout (FACO) facility in Italy, with some coming from the Fort Worth production line in the United States, and perhaps others being built in Switzerland itself as part of an offset package for RUAG...."

As elsewhere in Europe, the beginning of the war in Ukraine has started some tectonic plates shifting. The Liberal Radical Party wants defence spending to go up to 1% of GDP instead of 0.7% and pressure has been applied on the anti-F35A committee to withdraw their ballot initiative, which they have refused to do. The armed forces are concerned that the timing of it will make Switzerland lose it's slot, as they have till March next year to do so, and that's the deadline for signing the contract too. I expect more rumblings to happen as things get worse in the East.

Russian President Vladimir Putin is “unquestionably the best F-35 salesman of all time,” said Richard Aboulafia, managing director at AeroDynamic Advisory. The new defense appropriations bill funds 98 Lockheed Martin F-35s, an increase of 20 fighters from the Pentagon's proposal.
One hurdle, facing both the U.S. and European defense industry, is supply chain constraints. For example, the F-35 market “is clearly moving towards [producing] 200 [jets] a year, but [Lockheed Martin has] said, we really can’t do more than 156 for the next few years,” Aboulafia said.

The F-35’s skin is comprised of 4 layers; the carbon composite bottom layer that provides structural rigidity to the airframe, a new “fibermat” layer which is believed to incorporate the problematic conductive layer of earlier stealth coatings into a layer that’s part of the load-bearing structure (like the composite below it), a primer which is generally just used to help with coating adhesion and corrosion protection (but may have some radar absorbent quality), and then finally a topcoat that provides the jet it’s grey look, provides radar absorption qualities and reduces IR signature.

The image above comes from an unclassified 2017 presentation made by a USAF officer, with the presentation hosted by the National Center For Manufacturing Sciences.

How the layers exactly operate to reduce radar reflections, and what they’re comprised of / how exactly they’re produced is classified.

The F-35 also has radar absorbent elastomer-based seals for panels that need to be frequently accessed or actuated, as well as radar-absorbent tapes used to hide seams / gaps between panels that don’t need to be frequently accessed. The cockpit canopy also has coatings to prevent radar reflecting off the unstealthy cockpit internals, including the pilot. The composition of these canopy coatings and seals / tapes are naturally also classified.
 
Hill AFB’s 388th OSS exploring agile communications options for F-35A
Published March 31, 2022 By Micah Garbarino 388th Fighter Wing Public Affairs
HILL AIR FORCE BASE, Utah (AFNS) --

The 388th Fighter Wing’s Operations Support Squadron cyber Airmen are currently exploring high-speed communications options to support F-35A Lightning II Agile Combat Employment – operating from remote or austere locations.
The flow of information is critical in any war-time environment, and space and cyber capabilities almost completely dominate that arena for modern militaries. Speed and reliability in communications are demanding to support the cyber needs of the F-35's associated systems.
“We’re trying to get after what is Secretary [Frank] Kendall’s fifth operational imperative; ‘Defining optimized resilient basing, sustainment, and communications in a contested environment,’” said Lt. Col. Maxwell Cover, 388th OSS commander. “With the F-35, we are likely going to be using the ACE construct on any deployment, and we need resilient, redundant communications.”

For the first time, cyber Airmen used satellite and cellular internet capabilities to connect an F-35 deployed debrief facility (housing an Autonomic Logistics Information System server stack) and looped back into the Air Force network’s “central point of entry” for F-35 supply chain and logistics.
They did this with the help of cyber teams from Air Combat Command, ACC’s Agile Battle Labs initiative and Combat Communications, who analyze units’ operational needs and help them become more agile in the cyber realm.
“A huge piece of agile combat operations is hardening communications,” Cover said. “These teams are helping us develop better connectivity for the massive amounts of data that we need to push through ALIS.”

Current military satellite internet capability requires a longer lead time, and its fastest speeds are not sufficient for the amount of data required for remote F-35 operations, Cover said.
“If we have to get out the door quickly, that doesn’t work. When you look at operating out of a remote location for days, weeks, maybe longer, where we need ALIS, NIPR, and SIPR, it’s critical to have more agile communications,” Cover said.
Using a Flyaway Communications Terminal developed by the ABL team, the group harnessed speeds up to 30 times faster during the week-long test. It was more than enough to support ALIS as well as individual NIPR and SIPR connections.

The setup requires linking a small satellite-internet dish with a gateway router in a hard-sided case, then to a terminal that splits classified and unclassified data.
The gateway router has the capability to connect to a hardline network, satellite internet, or it also has several slots for cellular sim cards which can transmit data from many bands and regions. The router automatically selects which signal and network is fastest and transmit data simultaneously.
All of this is small enough to fit inside of an F-35’s travel pod, and virtually any Airman can be trained to set it up in less than 10 minutes, said Senior Master Sgt. Reid Beveridge, Agile Battle Labs senior enlisted advisor.

“Really, what we want to have is options for communications,” said 1st Lt. Corbin Meredith, 388th OSS, “We don’t have the infrastructure in every possible location, but with this we could go to SATCOM or cellular LTE and then go to offline capabilities as a last resort. The fact that anyone can be trained to set it up gives us more manpower options and brings another element to creating Multi-Capable Airman.”

The F-35 also has really good acceleration. The engine is a beast. If you start at say, 200 knots, the F-16 and F-35 side-by-side using full afterburners, the F-35 will reach Mach 1 faster. It will also beat an F-22 to Mach 1.
:oops:
"Kävelyvauhdista" transoonisen puoliväliin asti on siis aivan pitelemätön.

Ja F-35 jää vauhdista molemmille mach 1 jälkeen. Suunnittelu on optimoitu tuohon mach 1 tienoille ja ei ole supercruisea.

Tuosta linkistä bongattu toinen mielenkiintoinen juttu:
And because of our strategic location here in Alaska, we can get into the Pacific or Europe or anywhere in the northern hemisphere in a single-fighter sortie, using air-fueling. Billy Mitchell in the 1930s said, “Whoever holds Alaska holds the world.” That remains true today. That’s why we’ve got the F-35s here. The world map is very deceptive. We are closer to Beijing than Hawaii is to Beijing. Alaska is actually further west than Hawaii. We can also take the polar route. Our base is named after Ben Eielson, who was first to fly from North America to Europe over the North Pole.

Eli yllätys, yllätys: pohjolan puolustukseen voi USAF Europen lisäksi pölähtää US- vahvistuksia nopeimmin Alaskasta! Googlemaps ja monet muut kartat näytetään Mercatorin projektiona, joka ei näytä maapalloa realistisesti ja vääristää tiettyjen maiden kokoa (Grönlanti, Australia) lähellä projektion pystyakselin ääripäitä. Se tuppaa unohtumaan monesti.

Esimerkkinä: Lentomatka kalotin ylitse Gulfstreamilla kestää 7 h 34 min Fairbanksista(lähellä Eielsonia) Bodö:n. Matka on 5260 km. Vertailuna Eglin AFB- Bodö matkan kesto samalla speksillä 10 tuntia 35 min ja lentomatka 7351 km.
