US Plans for Supercharged F-35 (F-55) and F-22 Upgrades

Proposed F-55 Twin-Engine Fighter Jet

• 💡 Former President Donald Trump proposed a radical upgrade to the F-35, envisioning an "F-55" with a twin-engine design.
• 🚀 This concept aims to significantly enhance performance, potentially increasing thrust and top speed, and allowing for a larger payload.
• ⚠️ Experts express concerns, noting that converting the F-35 to a twin-engine aircraft would require a virtually complete redesign of the airframe and software, potentially increasing costs and complexity.
• ✈️ The F-35B variant, designed for vertical landing, is considered technologically unfeasible for a twin-engine conversion.

Potential F-35 Enhancements

• ✨ Lockheed Martin is exploring integrating technology from the Next Generation Air Dominance (NGAD) program into the F-35, aiming for "5th generation plus" capabilities.
• 💰 This initiative seeks to achieve 80% of 6th gen capability at 50% of the cost, making the F-35 more relevant for the future.
• 🛠️ The Block 4 upgrade program is already introducing significant software and hardware enhancements, including new sensors, improved electronic warfare, and increased missile capacity.
• ⚙️ Efforts are also underway to improve the existing F135 engine, focusing on increased thrust, fuel efficiency, and reduced maintenance costs.

"F-22 Super" Upgrade Plans

• 🌟 Trump also announced plans for an "F-22 Super," a modernized version of the F-22 Raptor, considered by many to be the best air superiority fighter.
• 💰 Requested funding of $10 billion over several years is earmarked for F-22 development, focusing on upgrades to weaponry, communications, navigation, pilot interface, and electronic warfare.
• 📈 These upgrades aim to maintain the F-22's relevance and air dominance through at least 2040, ensuring it remains competitive against future threats.

Rationale and Challenges

• 🧠 The push for these upgrades stems from a desire to maintain U.S. airpower superiority against global competitors like Russia and China.
• 💰 While twin-engine designs are often seen as safer due to redundancy, they also come with increased costs for manufacturing, maintenance, and operation.
• 🧐 The feasibility of Trump's F-55 concept is debated, with significant engineering challenges and redesign efforts required, contrasting with ongoing, more incremental upgrades to existing platforms.
