Japan Drops Apaches, Bets $70M on Drones Instead

Japan just put real money behind the idea that attack helicopters are finished. The country’s fiscal year 2026 defense budget, enacted on April 7, includes ¥11.1 billion ($69.7 million) to buy five “wide-area UAVs” for the Japan Ground Self-Defense Force, as Defence Blog reported.

The procurement is the first funded step in a plan to retire every attack and observation helicopter in the GSDF fleet and replace them with drones. Not supplement. Not augment. Replace.

What Japan Is Buying

The budget describes the wide-area UAV as a system that can detect surface vessels and other targets at long range and collect the intelligence commanders need to direct firepower. The Ministry of Defense didn’t restrict the procurement to unarmed platforms. That’s a significant detail, because both leading candidates carry weapons as standard configurations. Japan isn’t shopping for flying binoculars.

Two drones have completed formal Japanese government testing and evaluation. The Bayraktar TB2S, built by Turkey’s Baykar, is a satellite-equipped upgrade of the TB2 that became famous during the early months of the war in Ukraine.

It runs on a 100-horsepower Rotax 912 engine, stays airborne for roughly 27 hours, and carries up to 330 lbs of laser-guided munitions on four underwing hardpoints. Estimated unit cost is around $5 million. The GSDF Central Accounting Unit conducted a procurement survey for the TB2S in August 2023, and the Ministry of Defense confirmed to Jane’s that testing was completed during fiscal year 2025.

The IAI Heron Mk II, built by Israel Aerospace Industries, is the heavier option. It’s a medium-altitude, long-endurance platform that can fly for up to 45 hours at altitudes up to 35,000 feet. The Heron Mk II carries up to roughly 1,035 lbs of payload, including long-range radars, EO/IR sensors, ELINT, COMINT, and electronic support measures.

Maximum speed sits at about 160 mph. The Heron Mk II was spotted flying at Shirahama Airport in Wakayama Prefecture in August 2025, with Kawasaki Heavy Industries handling domestic operations. Testing wrapped up during fiscal year 2024. Estimated unit price is around $10 million, roughly double the TB2S.

The Ministry of Defense issued a second Request for Information on multi-purpose UAVs on January 30, 2026. Industry responses were due by March 12, meaning the ministry is now processing submissions and moving toward a selection decision.

Why Japan Is Killing the Attack Helicopter

This isn’t a budget cut disguised as modernization. It’s a doctrinal shift driven by what Japan has watched happen in Ukraine and the broader drone revolution.

The GSDF currently operates around 50 Bell AH-1S Cobras and 12 Boeing AH-64D Apaches. Japan originally planned to buy 50 to 80 Apaches, but costs spiraled and procurement stopped at 13 units (one was lost in a crash).

The observation helicopter fleet includes 37 Kawasaki OH-1s. The December 2022 Defense Buildup Program mandated phasing out all attack and observation helicopters, transferring their reconnaissance and strike roles to unmanned platforms. Retiring those manned fleets frees up roughly 1,000 personnel who can be reassigned elsewhere, a critical factor for a military that’s struggling to recruit.

The math driving this decision is straightforward. A drone that costs $5 to $10 million per unit and flies 27 to 45 hours without crew risk replaces helicopters that cost tens of millions, require two-person crews, and are increasingly vulnerable to man-portable air defense systems. Russia lost over 25% of its Ka-52 fleet to Ukrainian MANPADS. Japan looked at those numbers and apparently decided the manned attack helicopter belongs in a museum, not a defense budget.

The wider context is even more aggressive. Japan’s FY2026 budget commits over ¥100 billion (roughly $670 million) to accelerated unmanned systems deployment under a “quantity over quality” approach. The SHIELD program (Synchronized, Hybrid, Integrated and Enhanced Littoral Defense) alone receives ¥128.7 billion ($850 million) for developing unmanned aerial, surface, and underwater vehicles.

Under current five-year projections, funding for unmanned defense capabilities is set to increase tenfold, from ¥100 billion to ¥1 trillion. The GSDF is also establishing a dedicated unmanned systems department by the end of April 2026, staffed with 10 to 20 personnel focused on drone operations and AI integration.

Prime Minister Sanae Takaichi’s administration has announced plans to revise Japan’s three core security documents before the end of 2026, with drone-centric warfare identified as a central focus.

TB2S vs. Heron Mk II: The Trade-Offs

The two leading candidates offer fundamentally different capabilities at different price points. Choosing between them is a bit like choosing between a pickup truck and a semi. Both haul cargo, but the jobs they’re built for don’t overlap much.

The TB2S is lighter, cheaper, and combat-proven across multiple theaters. Its battlefield record in Ukraine, Azerbaijan, Libya, and Syria makes it one of the most operationally validated drones in the world.

For Japan’s southwestern island defense, where cost-per-sortie matters and the threat is primarily maritime surveillance and close air support, the TB2S offers a lot of capability for $5 million per unit. The satellite communications link on the TB2S variant specifically addresses Japan’s need for beyond-line-of-sight operations across its vast maritime approaches.

The Heron Mk II is a different animal entirely. Almost double the price, but it brings 45 hours of endurance versus 27, more than three times the payload capacity, and a significantly more advanced sensor and electronic warfare suite.

For persistent maritime surveillance over the East China Sea and monitoring Chinese military activity near the Ryukyu Islands, that endurance and sensor payload advantage could be decisive. The Heron Mk II can also carry ELINT and COMINT equipment for electronic reconnaissance, a capability that goes well beyond what the TB2S offers. My bet is on this one.

Japan could buy one or both. The budget authorizes five airframes, and a mixed fleet would give the GSDF both a cost-effective tactical strike platform and a high-endurance strategic ISR asset. Beyond these two, SUBARU signed a ¥660 million contract in December 2023 to study a vertical-takeoff multi-purpose UAV concept.

Yes, the car company. Japan’s defense industrial base has a habit of surprising people.

DroneXL’s Take

Here’s what I actually think, Japan just made the most consequential helicopter decision any major military has announced in years, and most people are sleeping on it.

Other countries are adding drones alongside their helicopter fleets. Japan is replacing helicopters with drones entirely. No new attack helicopter procurement. No manned-unmanned teaming bridge strategy. A clean break. That’s a level of commitment to the drone future that no other G7 military has matched. Everyone else is still dating drones. Japan just proposed.

The logic is sound. Japan’s geography demands persistent maritime surveillance across thousands of miles of coastline and island chains. Manned helicopters can’t provide that coverage without enormous crew costs and rotation schedules. A Heron Mk II flying 45-hour missions can cover more ocean than a fleet of Apaches could dream of, without putting pilots in range of Chinese or North Korean air defenses.

The TB2S brings something different: a cheap, proven strike platform that Japan can buy in volume and lose without losing crew. At $5 million per unit, Japan could buy 14 TB2S drones for the price of a single Apache. That’s the kind of math that makes procurement officers rethink their entire career.

But there are real risks here. Japan has never operated armed MALE drones in a military context. The GSDF is standing up a drone department with just 10 to 20 people. Integrating unmanned strike capability into a military that has spent 80 years defining itself by defensive restraint is a cultural shift as much as a technical one.

The hardware is the easy part. Building the doctrine, the training pipeline, and the institutional comfort with armed autonomous operations is going to take years.

The tenfold increase in unmanned funding through the five-year plan tells you Japan isn’t treating this as an experiment. It’s a permanent restructuring of how the GSDF projects power. And for a country staring across the East China Sea at a military that’s reportedly targeting one million tactical UAS by 2026, speed matters more than perfection.
