The F-35 Lightning II is evolving as one of the most impressive fighter planes of the 21st century. Technically, it is a flight-only model, but the F-35 is a flagship for innovation that goes beyond that; it is a big factor for local economies and a sign of defense partnership all over the globe. The capabilities of the F-35 were designed for combat in the skies. The F-35 integrates low observability, precise strike capability, and unparalleled situational awareness, which makes it the main component of today’s air force.
The plane was originally designed to accomplish the Joint Strike Fighter program’s aim to substitute several different aging aircraft of the Air Force, Navy, and Marine Corps with a single versatile platform. Lockheed Martin’s X-35 was declared the champion, resulting in three different versions of the same aircraft, each addressing different operational needs, i.e., F-35A for aircraft with conventional takeoff and landing, F-35B for aircraft with short takeoff and vertical landing, and F-35C for aircraft aboard a carrier. Though individual characteristics of each version have been described in detail, the three types have a lot in common. The common goal is the operation in demanding environments, the use of precision weapons, and unprecedented situational awareness for the pilots.
An international team has always distinguished the F-35 program. The United Kingdom, Canada, Italy, the Netherlands, Denmark, Norway, and Australia are among the nations that have either co-developed the project or are now involved in the procurement process. Foreign Military Sales have reached aircraft to countries such as Israel, Japan, and South Korea, thereby empowering the allied air capabilities worldwide.
One of the main reasons why the F-35 is still relevant is its adaptability. From the very beginning, the aircraft was designed to accept constant improvements. Block 4 modernization, which is going to be fueled by Technology Refresh 3 (TR-3) hardware, significantly ameliorates processing speed, sensor integration, electronic warfare capability, and weapons versatility.
The changes brought about in the F-35 are allowing it to run advanced software, introduce new sensors, and have a greater variety of precision munitions. Testing and evaluation are the main pillars that uphold the aircraft’s performance. For example, the 388th and 419th Fighter Wings units at Hill Air Force Base, the 56th Fighter Wing at Luke Air Force Base, and the 461st Flight Test Squadron at Edwards AFB, etc., ensure the jet operates reliably under real-world conditions.
Moreover, the F-35 is very good at linking the battlefields. By the use of its sensors and networking capabilities, it can gather and transfer information to the units on the ground, in the air, and at sea; thus, it acts as a force multiplier in combined operations. These exercises, operational deployments in the Middle East, etc., have been the means through which the aircraft has demonstrated its proficiency in diversified combat environments. The training of new pilots is still a very big task. In 2023, Luke Air Force Base marked the day its 1,000th F-35 pilot graduated, which was a clear indication of the magnitude of teaching and preparation that goes into mastering this advanced fighter.
Despite all the abilities, it comes at a very high cost. The total life-cycle cost of the program is estimated to be more than $2 trillion, which is primarily attributed to maintenance and modernization. Although a number of initiatives aimed at improving the reliability and controlling the costs are underway, the operating costs are still high, and sometimes they limit the number of flying hours a particular aircraft can fly annually.
The F-35 program also has a great impact on the economy of the country. The production of over 1,000 jets is the main cause of the annual contribution of around $72 billion to the U.S. economy, and it supports approximately 290,000 jobs that are a result of a network of 1,650 suppliers. The number of people employed in the program has risen by 35% since 2019, which is a clear indication of its importance in the defense industrial base.
From the technical perspective, the F-35 is fantastic. The F-35A is a single Pratt & Whitney F135 engine that produces 43,000 lbs of thrust and can carry up to 18,000 lbs of ordnance, which is powering the aircraft, and the plane is capable of flying at Mach 1.6. The F-35C, which is designed for carrier operations, has the widest wingspan and the largest landing gear in the family; thus, it is capable of catapult take-offs and arrested landings at sea. The pilot gets the best possible situational awareness through the use of the advanced sensor suite, i.e., AESA radar, the Distributed Aperture System, and the Electro-Optical Targeting System.
With the expected use of around 8,000 flight hours, the ongoing maintenance and modernization programs are aiming to keep the F-35 competitive way beyond the 2070s. Among the Block 4 upgrades, the specific ones that maintain the technological lead in the environment of growing threats are particularly essential.
Continuing, F-35 would be one of the major factors of the airpower of the U.S. and its allies, even after next-generation platforms, such as NGAD, have started to become operational. The main problem, however, is to conserve the money required for both sustainment and modernization while at the same time making sure that the aircraft has its edge intact in terms of readiness, capability, and technological superiority during the period of increasing strategic competition.
