Block 4 F35 - After years of low-cost development, the Block IIIF F-35 is scheduled to enter service in 2019. However, the Pentagon is already looking into adding new developments to a base model called the Block. 4 - a major upgrade costing $16 billion.
The accompanying article describes key software and hardware improvements to the F-35's sensors, communications and propulsion systems, as well as Block 4's critical funding levels. Here we consider new weapon systems due to the addition of Block 4, which will enable the F-35 naval attack, air - and space skills.
Block 4 F35
A key addition was the GBU-54/B Stormbreaker, also known as the Small Diameter Bomb II. Like the GPS-guided GBU-39 SDB I previously added to the F-35, the 208-pound Stormbreaker is single-diameter from 15 to 18 cm, allowing eight F-35s loaded with local weapons to be placed. If theft is not a concern, sixteen more can be kept in the wings.

However, the SDB II is capable of changing direction to hit moving targets in all weather conditions up to forty-five miles away thanks to its three mode guidance options: an uncooled infrared seeker, a millimeter wave active radar, until home. to the target illuminated by the laser. It has a data link that allows two-way communication with the launch F-35, allowing it to adjust or cancel the strike. The Stormbreaker's 105-pound warhead can land within a meter of its target on average and is effective against personnel, boats and land vehicles - it falls back with large chariots armed with heavy weapons.
The Pentagon expects the Stormbreaker, combined with the F-35's advanced electro-optical targeting system and synthetic aperture radar, to enable surveillance in inaccessible areas — that is, areas where military vehicles are prohibited from passing. in terms of a no-fly zone to ban military aircraft.
That said, the Stormbreakers don't come cheap at $115,000 each, so Block 4 may also feature the short-range GBU-54 Laser JDAM. The 500-pound laser and GPS-guided bomb costs only about $20,000 and can attack moving targets.
Another weapon available for full integration is the AGM-154 JSOW-C1, a multi-thousand pound glide missile with data link and infrared tracking for guidance designed to engage and destroy mobile maritime targets up to seventy miles away. when fired at high altitude. This gives the Navy F-35C greater maritime attack capability.

More expensive long-range weapons like the JASSM-ER and Long Range Anti-Ship Missile can only be added to a future Block 5 or Block 6 F-35. While Lightning can close in on defensive targets, linking such long-range weapons is a bit of a disappointment. Now four generations of fighters and pirates can benefit from their use.
In air-to-air mode, the F-35B is positioned to be compatible with the Block II model of the AIM-9X short-range multipurpose missile, which the pilot can visually aim at the helmet. The Block II's lock-on after-launch capability means the F-35 can be launched from the internal vehicle without locking and then, based on guidance sent over the F-35 data link, turns 180 degrees to a target detected by the radar. or using the rider's knowledge of the helmet before coming back to kill with his heat detector.
Speaking of the helmet-mounted display system, which uses cameras to allow pilots to "see" their own aircraft, it needs to be modified for poor visibility and also allow drivers to "look" directly behind them without actually turning.
The addition of dual fuel tanks for the F-35's vehicles will also allow it to carry six long-range AIM-120 air-to-air missiles instead of four, helping to reduce the risk of the F-35 being affected. through more airborne enemies.

Block 4 is expected to add ground weapons requested by other F-35 pilots, including the British SPEAR cruise missile and the Meteor anti-aircraft missile (which is expected to be one of the longest-range air-to-air missiles in service). , Turkish SOM cruise missiles and Norway's Kongsberg Joint-Strike Missile, capable of hitting land or sea from a range of 170 miles with a 500-pound warhead. The Norwegian F-35s will also have special towing parachutes to facilitate landing on snowy Scandinavian airstrips.
The F-35 Block 4 may have upgraded engines designed to power the new electronics. This remaining energy can be converted into energy weapon lasers that can be used to shoot down incoming air-to-air missiles, early launch ballistic missiles, and enemy fighters. The Air Force plans to begin testing bomber-born weapons and lasers in the early 2020s, meaning integration of F-35 weapons will not be possible until after Block 4.
The most dangerous weapon that Block 4 brings to the F-35 is actually the B-61 Mod 12 nuclear gravity bomb, whose tail fins can adjust the bomb's trajectory to hit an average of 30 meters from a selected GPS coordinate. The B-61 can choose between 0.3 and 50 kilotons and has bunker penetration capabilities. The combination of precision and power means it can threaten enemy command and control centers and complex missile sites. As part of the NATO deal, US B-61 bombers will also be available to attack F-35 partners in NATO.
The future frontline capability of the F-35 is to penetrate outer airspace with less space and deliver a simple nuclear weapon that will be a source of enemy military numbers, for better or for worse.

Decisions to escalate into conventional nuclear war - that is, using small nuclear weapons against a front-line military - can be very pleasant considering the death toll, a deadly F-35 response. On the other hand, it could potentially increase nuclear strikes on the F-35 fleet. In addition, opponents are unsure whether the F-35's low-altitude radars can be fired from conventional weapons or from nuclear weapons, which will quickly escalate into nuclear war.
Overall, the Block 4 upgrade is intended to round out the F-35's ability to engage a wider range of targets and fulfill promises to other F-35 partners to support their local weapons. But if the Department of Energy can find the necessary funds and implement a robust development plan, it will deliver Block 4 on time (and apparently not over budget).

He also worked on refugee education, rehabilitation and resettlement in France and the United States. He currently writes for War Is Boring on security and military history. The expected timing of the F-35 fighter jet renewal in the block could influence the Air Force's decision to extend the procurement process for the F-35A model, according to a report on the future of the airborne military jet force released by the Mitchell Institute - and space travel. The report is called
, and said that delaying delivery of Block IV until 2029 could affect delivery and sales plans for the aircraft.

"Block 4 is a combination of technology, engineering and software upgrades that will significantly improve the combat effectiveness of the F-35," the report said. "The F-35 was designed and built around a concept to increase aircraft capabilities."
Many of the jet fighter's combat capabilities were woven into software developed to enhance the jet's technological capabilities. For example, the Block 3F F-35 program increased the JSF's weapon capacity, giving it the ability to drop a small-diameter bomb, the 500-pound Joint Direct Attack ammunition, and the AIM-9X Sidewinder missile . .
The delays associated with Block IV run counter to the Air Force's plan to quickly change the software upgrade process as upgrades and integrations accelerate time-to-use. Air Force officials said the new program will not be repeated in windows separated by a year or more, but will continue on a "ready" basis. This strategy complements a comprehensive software upgrade plan and accelerates innovation, security defenses, intelligence operations, situational awareness and weapons upgrades.
Due to some recent software improvements, the F-35 fighter jet can fire the Sidewinder missile "off boresight" along with a growing number of other weapons. In subsequent years, the Block IV upgrade will allow the jet fighter to launch the Small Diameter Bomb Increment II known as the Stormbreaker.

Given the importance of quickly adding new software to improve the aircraft's ability to fight new wars, the report cited concerns about the timeframe for Block IV's arrival. Block IV is needed in any conflict with China, the report said.
"Performance analysis has shown that the Block 4 configuration is more effective in the conflict with China," the report said. “However, the problems in training all the Block 4 technique has given the entire Block IV class at least 2029 and that is important for the
