On May 15, 1972, the SR-71 Blackbird experienced critical failures while flying over Hanoi, Vietnam. Major Tom Pugh managed to regain control and relight the engines, allowing the aircraft to continue its mission. A North Vietnamese general later revealed that they refrained from engaging the aircraft due to a belief it was booby-trapped with a nuclear weapon, which was false.

The D-21B drone, developed by Lockheed Skunk Works, was used by the U.S. Air Force for reconnaissance missions over Communist China from 1964 to 1971. Despite its advanced capabilities, including Mach 3 speed, the program was canceled after four unsuccessful missions. A total of 38 units were produced, with some preserved in museums.

The SR-71 Blackbird and A-12 Oxcart conducted reconnaissance missions over the Middle East, North Korea, and Vietnam from the 1960s to the 1980s. They provided critical intelligence on military threats, including Iranian Silkworm missile sites during the Iran-Iraq War. The A-12 was noted for its speed, surpassing that of the SR-71, and both aircraft played significant roles in U.S. military operations.

Japan's Air Self-Defense Force scrambled fighter aircraft on March 28 in response to a Chinese Y-9 military patrol aircraft detected flying southwest of Okinawa. This aircraft is assessed to be a new or modified variant, marking a significant development in regional military dynamics. The Japanese Ministry of Defense stated it will enhance intelligence and surveillance operations in response to such military movements.

Two suspicious individuals approached a military position in the Deep Mountains, prompting a drone to lock onto them. New recruits at the Rocket Army Training Center are undergoing comprehensive training, including physical conditioning and skills development, to enhance their operational capabilities.

A bionic manta ray drone developed by the Ningbo Research Institute of Northwestern Polytechnical University is operating underwater to locate explosives. It utilizes advanced sonar systems for terrain mapping and can travel hundreds of kilometers on a single charge. This technology showcases significant advancements in underwater reconnaissance capabilities.

The L30 unmanned boat patrol group conducted autonomous patrolling and interception exercises in Zhuhai waters. These boats, equipped with advanced optical and radar systems, demonstrated their ability to form formations and intercept intruding vessels. The operation was guided by the local water command center, showcasing the capabilities of unmanned systems in naval engagements.

China is conducting extensive undersea mapping and monitoring operations across the Pacific, Indian, and Arctic oceans, utilizing the Dong Fang Hong 3 research vessel and numerous sensors. This effort aims to enhance its submarine warfare capabilities against the United States, focusing on strategically important areas such as Taiwan, Guam, and the Malacca Strait. The operation involves dozens of research vessels and is part of a broader military strategy to gather intelligence on underwater terrain and conditions.

China is conducting extensive undersea mapping and monitoring operations across the Pacific, Indian, and Arctic oceans using dozens of research vessels and hundreds of sensors. The Dong Fang Hong 3 has been active near Taiwan and Guam, gathering data crucial for submarine warfare against the U.S. and its allies. This initiative reflects China's military strategy to enhance its naval capabilities and gather intelligence on underwater conditions.

The SR-71 Blackbird operated from January 1966 until its retirement in 1998, successfully conducting high-speed reconnaissance missions. It was designed to evade enemy missiles, achieving this feat by outrunning threats, as it was shot at 4,000 times without being hit. The aircraft's advanced design and capabilities made it a critical asset for the U.S. Air Force during the Cold War, gathering intelligence on various geopolitical hotspots.

A French sailor revealed the location of the aircraft carrier Charles de Gaulle while logging a run on a fitness app on March 13. The carrier was located approximately 100 kilometers south of Turkey and west of Cyprus, heading to the Middle East. This incident highlights ongoing security risks associated with fitness tracking applications for military personnel.

DroneShield announced a partnership with Robin Radar Systems on 18 March 2026 in Sydney, aimed at enhancing radar interoperability for counter-drone technology. This collaboration will expand radar options for defense and public safety, utilizing Robin's 360°, 3D radar technology. The partnership focuses on improving airspace security and operational flexibility through advanced sensor integration.

This collaboration aims to improve airspace awareness and detection capabilities across defense and public safety sectors, utilizing Robin's advanced 360°, 3D radar technology. The integration of these systems is expected to provide operators with a more flexible and effective airspace security architecture.

Beijing University of Science and Technology is developing four types of flapping drones that mimic birds and insects for flight. The eagle-mimicking drone can accurately identify and track ground targets, achieving a maximum flight time of 256 minutes. Researchers aim to improve the drones' intelligence and autonomous flying capabilities.

Taiwan's ROCS Hai Kun (SS-771) is operational in the Taiwan Strait, designed to deter potential Chinese invasions. Equipped with advanced stealth technology, it integrates Mark 48 torpedoes and Harpoon missiles for maritime defense. The submarine's capabilities enhance Taiwan's intelligence, surveillance, and reconnaissance efforts against the People's Liberation Army Navy.

China unveiled the CH-7 stealth drone at the Zhuhai Airshow in November 2024, designed for high-risk ISR and electronic warfare. The drone can penetrate contested airspace at Mach 0.5, transmitting targeting data to combat units. It signifies a major advancement in the People's Liberation Army Air Force's capabilities for conducting surveillance and electronic warfare against adversaries.

The SR-71 Blackbird conducted high-speed reconnaissance missions, including a notable flight from Kadena Air Base in Okinawa to Beale Air Force Base in California, which created the illusion of time travel due to crossing the International Date Line. The aircraft, operational in the 1990s, was capable of speeds exceeding Mach 3 and altitudes above 85,000 feet, making it a vital intelligence platform during the Cold War. It was retired in 1998 due to high costs and advancements in satellite technology.

The People's Liberation Army Air Force (PLAAF) conducted a massive air exercise involving over 200 aircraft across eight air bases in Western China in late 2025. This exercise, known as Red Sword, spanned an operational area of 1,200 nautical miles and included various aircraft types such as J-20 stealth fighters and H-6 bombers. The exercise is noted for its scale and secrecy, reflecting the PLAAF's growing capabilities.
