1. Organization size and personnel Active personnel (SDF authorized strength): Approximately 251,000 Reserve personnel: Approximately 56,000 Defense budget: With the fundamental strengthening of defense capabilities, the budget is trending upward, moving beyond the conventional "1% of GDP framework" toward a target of "2% of GDP." 2. Main strength and advantages of each Self-Defense Force [Maritime Self-Defense Force] (High anti-submarine, air defense, and minesweeping capabilities) For the island nation of Japan, the equipment and proficiency of the Maritime Self-Defense Force are among the best in the world. Major vessels: Approximately 150 or more Destroyers (including Aegis ships): Approximately 40 (Aegis ships with ballistic missile interception capability are being progressively expanded) Helicopter-carrying destroyers: 4 (The "Izumo" and "Kaga" are undergoing conversion into de facto light aircraft carriers capable of launching and recovering F-35B fighters) Submarines: 22-boat structure (extremely quiet conventional-powered submarines such as the "Taigei-class" and "Soryu-class") Strengths: "Anti-submarine warfare (ASW) capability" and "minesweeping (mine removal) capability" comparable to the U.S. Navy. [Air Self-Defense Force] (State-of-the-art air power and warning and surveillance network) It maintains a robust air defense system, including scramble launches against airspace violations. Number of operational aircraft: Approximately 400 or more (approximately 1,400 total aircraft) Main fighter aircraft: F-15J (upgraded), F-2, and the latest fifth-generation stealth fighter F-35A/B (being introduced sequentially), F-3 (under development) Warning, surveillance, and transport: Operates numerous early warning and control aircraft (AWACS) such as the E-2D and E-767, and aerial refueling aircraft such as the KC-46A. Strengths: The Japan Aerospace Defense Ground Environment (JADGE) system covering all of Japan, and high operational capability of fighter aircraft. [Ground Self-Defense Force] (Mobilization and remote island defense) Shifting from Cold War-era heavy anti-tank equipment to "remote island defense and rapid response mobility" centered on the Nansei Islands. Main equipment: Tanks: Approximately 700 (domestically produced Type 10 and Type 90 tanks) Armored vehicles and mobile combat vehicles: Wheeled armored vehicle groups capable of high-speed movement on public roads, such as the Type 16 Maneuver Combat Vehicle Special forces and amphibious units: Has organized the "Amphibious Rapid Deployment Brigade," called Japan's version of the Marine Corps, and retains the capability to retake remote islands using AAV7 amphibious vehicles and V-22 Ospreys.
