    David J. Bercuson: Why Japan is building its military, fast

    David J. Bercuson With 18 diesel electric submarines, four so-called “helicopter destroyers” that look suspiciously like small aircraft carriers, 43 destroyers and destroyer escorts, 25 minesweepers and training ships, fleet oilers, submarine rescue ships and other vessels, Japan's navy — the Maritime Self-Defense Force — is the second largest in Asia and one of the largest in the world. It is also highly advanced technologically and is growing all the time. The two 27,000 ton Izumo-class helicopter destroyers, the largest in the fleet, with flat flight decks and islands on the starboard side of the vessels, are small compared to the United States Navy's Nimitz-class aircraft carriers (approximately 100,000 tons) or Britain's new Queen Elizabeth-class carriers (65,000 tons). But if equipped with the new short-take-off-and-vertical-landing F-35B stealth fighter they will still pack a powerful punch. And Japan is considering adding more of these aircraft carriers to its fleet and advanced U.S.-style Aegis class destroyers, capable of shooting down medium-range ballistic missiles. The irony in all of this is that Japan's post Second World War constitution still contains a provision — Article 9 — that prohibits it from possessing any offensive military capability. In the early 1950s, Japan began to build its self-defence forces and now has a powerful navy, a modern medium-sized air force that will soon fly the F-35 along with specially built F-15s, alongside more than 300 fighter aircraft and 50,000 personnel, and a growing land army and marine sea landing capability. Are these military assets “defensive” in nature? Partly, but aircraft carriers, high-speed destroyers, modern fighter aircraft and assault ships are surely as offensive as they are defensive. And Japanese Prime Minister Shinzo Abe has made it plain that in less than two years, he intends to seek to change the Japanese constitution to drastically curtail any obligation Japan has to maintain a purely defensive capability. In other words, he will ask the Japanese people and legislature to bless what Japan has already done. That could be more problematic than people realize. Like Germany, Japan suffered greatly in the Second World War. Virtually all its great cities were levelled either with atomic bombs (Hiroshima and Nagasaki) or fire raids that were carried out by giant B-29 bombers at low altitude at night. The attacks burned the heart out of Japan's cities. In March 1945, 100,000 people were killed in one night in a fire raid on Tokyo and many acres of the city were burned to the ground. Submarine blockades of Japan drastically curtailed food and fuel supplies. Hundreds of thousands of Japanese soldiers were killed either in the United States' march across the Pacific or in the Russian invasion of Manchuria near the end of the war. Japan was a prostrate nation by the end of 1945 and its ancient system of government was a shambles.

  • Light as a form of defence? Laser brings down unwanted drones

    Light as a form of defence? Laser brings down unwanted drones

    June 8, 2020 - Almost 300,000 km per second. That's the speed of light, and also the speed of laser light. Faster than any projectile. A laser is also accurate and always hits its target. This means it should be possible to bring down unwanted drones quickly and cheaply. In a laboratory set-up for weapon systems, TNO is already seeing promising test results with a high-energy laser. From an innocent toy to an offensive weapon: that's what happens when malicious people attach explosives to drones. The fact that improvised explosive devices like this can inflict significant damage was confirmed yet again last September, during the attacks on Saudi Arabian oil installations. GATWICK AIRPORT PLAGUED BY DRONES Even without explosives, drones can still cause major problems. In 2018, at Braitains Gatwick airport, a few simple and inexpensive drones proved capable of causing hours of disruption to air traffic. “The Netherlands has its own counter-drone research programme. The problem is being taken very seriously.” COUNTER-DRONE RESEARCH PROGRAMME Several countries across the world, including the Netherlands, are developing solutions for the problem of drones. Last year the Netherlands launched its own counter-drone research programme, spearheaded by the Ministry of Defence, the National Police and the National Coordinator for Counterterrorism and Security (NCTV). The problem is being taken very seriously and is therefore high on the agenda. UTMOST CARE “The first challenge is to quickly detect and identify an incoming drone”, says Patrick Keyzer, who heads up TNO's research programme. “If a drone appears to represent a genuine threat, we have to disarm it as quickly as possible. Of course, it must be done with the utmost care and we need to ensure that we inflict as little unintentional damage as possible.” “TNO is testing a high-energy laser capable of burning a hole in thick steel plate in just a few seconds” ENOUGH FIREPOWER Using a laser is one of the possibilities for disabling drones. “It's a highly effective method”, confirms Federica Valente, Business Developer for TNO's high-energy laser research. In a heavily-secured bunker, her colleagues are testing a high-energy laser capable of burning a hole in thick steel plate in a matter of seconds. “That's obviously more than enough firepower to bring down drones.” LESS THAN A EURO A SHOT “This kind of laser is also extremely accurate and cost-effective”, she continues. “To fire it, you only have to pay for the energy: less than a euro each time. A laser is also very flexible, enabling you to monitor the drone's every movement at relatively low cost.” “In addition to using a laser, we can also take control of the drones or use jammers” TOOLBOX “A laser weapon certainly has numerous advantages”, agrees Keyzer. “But we need to carefully assess the setting and situation in which a drone appears. It's important to have several options at our disposal for disabling drones responsibly. This is why we're currently developing and researching several different solutions. In addition to using a laser, we can also take control of the drones or use jammers. So, it's not a case of ‘one solution fits all'. Nevertheless, the emergence of a laser weapon will help enormously in combating the threat of drones.” The laser weapon is just one of the weapon systems that TNO is researching. The aim of these innovations is to protect those who protect us. Read more about it on the ‘Weapon Systems' page.
