8-9-2023 (SINGAPORE) The Republic of Singapore Air Force (RSAF) has officially unveiled its newly upgraded F-16 fighter jets armed with the state-of-the-art Python-5 missiles, marking a significant enhancement in its air defense capabilities. These short-range air-to-air missiles, developed by Israeli defense firm Rafael Advanced Defense Systems, are renowned for their precision and advanced features.
The Python-5 missiles have a remarkable range, capable of destroying airborne threats within a 20-kilometer radius, making them a formidable asset for the RSAF’s aerial defense. A notable feature of these missiles is their ability to allow pilots to lock onto enemy aircraft and fire without the need to alter their aircraft’s direction, providing a tactical advantage in air combat situations.

While reports of the RSAF deploying Python-5 missiles surfaced several months ago, the RSAF has now confirmed their integration into its F-16 fleet. The upgraded F-16s started entering service in June 2021 and are expected to remain operational for at least another decade, having served since 1998. These mid-life upgrades commenced in 2016, and the RSAF has long-term plans to replace its F-16 fleet as they approach global obsolescence beyond 2030. Earlier this year, Defense Minister Ng Eng Hen announced the acquisition of 12 F-35B fighter jets, expected to be delivered by the end of this decade.
The addition of Python-5 missiles to the upgraded F-16s brings these fighter jets on par with more modern aircraft, ensuring they remain a formidable force in the region. The Python-5 is a versatile dual-purpose missile suitable for both air-to-air and surface-to-air missions, making it a valuable asset for the RSAF’s multifaceted defense strategy.
The Python-5 boasts an “exceptional kill probability and excellent resistance to countermeasures, irrespective of evasive target maneuvers,” according to Rafael’s official website. Its advanced electro-optical and imaging infrared seeker offers high off-boresight capability, enabling precise targeting even at extreme angles away from the aircraft’s line of sight.
Moreover, pilots of the upgraded F-16s will utilize the Joint Helmet Mounted Cueing System, allowing them to engage targets from any angle or distance by simply turning their heads to look at the enemy. This feature eliminates the need for traditional missile-firing positions behind enemy aircraft, enhancing the fighter jets’ combat effectiveness.
The Python-5’s dual waveband infrared seeker enables RSAF pilots to acquire and engage small, low-signature targets under adverse weather conditions, both day and night. Its “lock-on after launch” capability further enhances its effectiveness, allowing missiles to lock onto targets even after they have been launched.
In addition to the Python-5, the RSAF’s upgraded F-16s are equipped with other advanced capabilities, including US-made air-to-air missiles like the AIM-9 Sidewinder and AIM-120. While these are slightly older than the AIM-9X Sidewinder, they remain formidable assets in the RSAF’s air defense arsenal.
