By: Mike Yeo MELBOURNE, Australia — Japan's defense budget for the next fiscal year will set a record high for the seventh year running, although the approved figure is still lower than that requested by the Defense Ministry. The country's Finance Ministry approved a budget of $51.5 billion for the Defense Ministry, which is $3.5 billion lower that the Defense Ministry requested in September. Funds expected to upgrade Japan's fleet of fighter jets were removed as part of the reduction. Specifically, the request for $205 million to upgrade the Japan Air Self-Defense Force's F-15J Eagle interceptors was cut in full. The upgrade would have seen the interceptors get new radars and mission computers, and equipped with standoff land-attack missiles. But local media reports said the escalating costs of nonrecurring engineering work prompted a rethink of the program. Japan requested and received the U.S State Department's approval for the upgrade of up to 98 F-15Js for an estimated cost of up to $4.5 billion. The work would have been carried out by F-15 manufacturer Boeing in conjunction with Mitsubishi Heavy Industries, which built the Japanese jets under license in the 1980s. Plans to buy two more Kawasaki C-2 airlifters and 25 wheeled Type 16 combat vehicles were also impacted, with the adjusted budget now allocating funds for only one C-2 and 22 Type 16. However, plans for Japan to acquire four more Lockheed Martin F-35A conventional-takeoff-and-landing jets and two F-35B short-takeoff-and-vertical-landing jets over the next fiscal year will go ahead. Japan has an eventual requirement for 105 F-35As and 42 F-35Bs, which makes it potentially the biggest operator of the Joint Strike Fighter outside of the United States. The country announced earlier this week that it selected Lockheed Martin to partner with local industry in the development of a next-generation fighter jet. The approved budget also allocates $323 million to increase the range of the indigenous truck-launched Type 12 anti-ship missile, with Japan seeking to eventually use the missile from aircraft and ships to strike naval targets from standoff distances. Budget documents also confirmed Japan is conducting a feasibility study on building two more destroyers fitted with the Aegis combat system and radars to beef up ballistic missile defense. The move follows the decision to cancel plans to build two Aegis Ashore systems on Japanese soil due to the danger of boosters from the missile interceptors falling onto populated areas. Previous local media reports said the proposed destroyers would use the Lockheed Martin AN/SPY-7(V)1 radar, which was also selected by Japan for the canceled Aegis Ashore systems. The budget is for the forthcoming Japanese fiscal year, which starts April 1, 2021. https://www.defensenews.com/global/asia-pacific/2020/12/21/japan-releases-record-high-budget-but-not-all-programs-made-the-cut/

Todd South The gun that will replace both the M249 Squad Automatic Weapon and the M16/M4 rifle/carbine weapons — and add a new, widely distributed caliber to the U.S. military inventory for the first time in decades — is less than two years away. The Next Generation Squad Weapon finished its first prototype test event in September. The three previously selected offerings came from Sig Sauer, Textron Systems and General Dynamics Ordnance. Brig. Gen. David Hodne, Infantry School commandant and Soldier Lethality Cross Functional Team director, along with Brig. Gen. Anthony Potts, head of Program Executive Office Soldier, gave updates to Army Times ahead of the Association of the U.S. Army Annual Meeting and Exposition. Concurrently, the Army in April has also selected two companies, L3 Technologies and Vortex Optics, to compete for the fire control for the weapons system. Sig Sauer's design looks much like a conventional assault rifle while GD is using a bullpup design, which shortens the length by building the magazine feed into the weapon stock. Textron has built its weapon around the cartridge, which is unique to them, a cased telescope item that has the projectile inside of the casing to reduce weight. Back in April, each of the companies provided 15 rifles, 15 automatic rifles and 180,000 cartridges using the government-developed 6.8mm projectile. The 6.8mm projectile was chosen after decades of testing and evaluation showed that 5.56mm lethality at mid-ranges on the battlefield was inadequate and existing 7.62mm could be outperformed by the 6.8mm round and save weight for the soldier. The new caliber also gives the soldier both a rifle and automatic rifle firing the same round, both effective past the 600m mark of existing light calibers. Following the September testing, the companies will have six months until their next prototype test, scheduled to begin in February. During the annual Maneuver Warfighter Conference at Fort Benning in Georgia, Maj. Wyatt Ottmar, project officer over NGSW for the Soldier Lethality CFT, laid out some of the recent developments and next steps for the weapons system. Ottmar noted that Sig Sauer provided a combined steel lower and brass upper ammunition cartridge to reduce weight. A contract is expected to be awarded to one of the three companies this coming fiscal year with fielding to start in the fourth quarter of fiscal year 2022, or sometime between August and October 2022, to Infantry, Stryker and Armor Brigade Combat Teams. Ultimately, the weapon will be fielded to all close combat forces, including special operations forces, infantry, combat engineers and scouts. The fire control is expected to field six months ahead of the weapon, Potts said. That will allow the NGSW producer to better integrate the optic with the weapon. https://www.defensenews.com/news/your-army/2020/10/14/the-armys-saw-and-m4-replacement-is-headed-to-troops-by-2022/
