F-35 Lightning II vs. JAS 39 Gripen

The Lockheed Martin F-35 Lightning II is a family of single-seat, single-engine stealth multirole combat aircraft developed by Lockheed Martin, with principal partners Northrop Grumman and BAE Systems. Designed to perform air superiority and strike missions, it also provides electronic warfare and intelligence, surveillance, and reconnaissance capabilities. The F-35 has three main variants: the conventional takeoff and landing F-35A, the short take-off and vertical-landing F-35B, and the carrier-based F-35C​​.

Production History: The F-35 was the culmination of the Joint Strike Fighter (JSF) program, which merged various combat aircraft programs from the 1980s and 90s. It descends from the Lockheed Martin X-35, which in 2001 won the JSF competition over the Boeing X-32. The program has been supported by the United States, along with NATO and close U.S. allies. Despite the criticism for its size, complexity, and cost, the F-35 first flew in 2006 and entered service with the U.S. Marine Corps F-35B in July 2015, followed by the U.S. Air Force F-35A in August 2016 and the U.S. Navy F-35C in February 2019. Over 1000 units have been produced since 2006​​​​.

Design Features: The F-35 is known for its stealth capabilities, advanced sensor package, and electronic sensors like the Electro-Optical Distributed Aperture System (DAS) and the Electro-Optical Targeting System (EOTS). The F-35 is designed to replace aging fighter inventories such as the U.S. Air Force F-16s and A-10s, U.S. Navy F/A-18s, and U.S. Marine Corps AV-8B Harriers and F/A-18s​​​​.

Operational History: The F-35 first saw combat in 2018 with the Israeli Air Force. It is planned to be a cornerstone of NATO and U.S.-allied air power, with the U.S. planning to buy 2,456 F-35s through 2044. The aircraft is expected to operate until 2070. It is designed to provide pilots with unsurpassed situational awareness, positive target identification, and precision strike in all weather conditions​​.

F-35 Lightning II vs. F-22 Raptor

Stealth and Air Superiority: While both aircraft offer advanced stealth capabilities, the F-22 is optimized for air superiority with higher maneuverability and speed. In contrast, the F-35 emphasizes multirole flexibility, with superior sensor fusion and strike capabilities.

Network-Centric Warfare: The F-35 is designed from the ground up for network-centric warfare, with the ability to share information seamlessly with allied forces. The F-22 has significant data link capabilities but does not match the F-35's level of sensor integration and information distribution.

F-35 Lightning II vs. Su-57 "Felon"

Multirole Versatility vs. Air Dominance: The Su-57 is Russia's answer to fifth-generation capabilities, focusing on air dominance with some ground attack capabilities. The F-35, while capable in air-to-air combat, provides a broader multirole function.

Global Deployment and Support: The F-35 has seen widespread adoption among U.S. allies, benefiting from a multinational development program. The Su-57, while a technological showcase for Russia, has not achieved the same level of international deployment.

The JAS 39 Gripen, manufactured by the Swedish aerospace company Saab, is a fourth-generation multi-role fighter aircraft known for its exceptional performance, advanced avionics, and cost-effectiveness. Introduced in 1997, the Gripen was designed to meet the diverse needs of modern air forces. Its name, "Gripen," which means "the Griffin" in Swedish, symbolizes its strength and flexibility.

Production History: Development of the JAS 39 Gripen began in the early 1980s, with the goal of producing a modern, affordable fighter that could replace Sweden's aging fleet of Viggen and Draken aircraft. The Gripen's design incorporates a single-engine, canard-wing configuration for enhanced maneuverability and short takeoff and landing (STOL) capabilities. Over the years, the Gripen has been developed in iterations, including the A/D, C/D, and latest E/F variants.

Design Features: The Gripen features a delta wing and canard configuration for superior aerodynamic performance, allowing for tight turn rates and high agility. It is powered by a Volvo Aero (now GKN Aerospace Engine Systems) RM12 engine, providing the ability to supercruise under certain conditions. Its design emphasizes ease of maintenance and low operational costs, making it one of the most cost-effective fighters in its class.

Operational History: The Gripen has participated in various international missions and exercises, demonstrating its capabilities in both air-to-air and air-to-ground operations. Its operational flexibility was notably showcased during the 2011 Libyan Civil War, where it conducted reconnaissance missions as part of NATO operations.

Technological Advancements: The Gripen incorporates some of the latest advancements in fighter technology, including digital fly-by-wire flight controls and a highly integrated sensor package. In contrast, the F/A-18 Hornet, while continuously upgraded, is based on older design principles but maintains robust multi-role capabilities.

Cost-Effectiveness and Operational Efficiency: The Gripen is renowned for its lower operational costs and maintenance requirements, designed to be serviced by personnel with minimal specialized training. The F/A-18, while highly capable, generally requires more resources for operation and maintenance.

JAS 39 Gripen vs. Eurofighter Typhoon

Design Philosophy and Size: The Gripen, designed for cost-efficiency and flexibility, is smaller and lighter than the Eurofighter Typhoon, which is focused on raw performance and advanced capabilities. This makes the Gripen more suited for countries looking for high efficiency and lower lifecycle costs.

Airframe and Performance: While the Typhoon boasts superior high-speed performance and agility, thanks to its larger size and more powerful engines, the Gripen excels in versatility, ease of maintenance, and the ability to operate from shorter runways.
