Mac Jee Defesa, part of Brazil's Mac Jee Group, is finalising the development of a wing-assisted guidance kit that converts an air-droppable, unguided 500 lb low-drag general-purpose bomb into a long-range, air-to-ground all-weather precision-guided weapon.

The Dagger kit comprises a guidance module consisting of the electro-optic/infrared payload with Medium-Wave Infrared camera, delivering a Circular Error Probable of less than 1 m, a sensor stabilisation system, an INS/GNSS unit for autonomous mid-course navigation, a guidance and navigation computer system, a computer vision system, and a crypto dual-band frequency-hopping datalink system. The Dagger system also features quick-fold-out mid-body wing-set kit with an energy storage and distribution system, while the rear module comprises an electronic fuze and interlock, dual-band telemetry and command system, and the control and actuation system.

US MDA plans to turn on Polish Aegis Ashore site in June, after years of delay

The US Missile Defense Agency (MDA) is planning for a 5 June ‘light-off' to turn on and test its long-delayed Aegis Ashore missile interceptor system in Poland, according to MDA Director Vice Admiral Jon Hill.

US Navy sailors are ‘aboard' the system in Poland and the radar arrays are up, and “full functional checks all through the system” will begin after 5 June, Vice Adm Hill said on 23 May at the Center for Strategic and International Studies.

Those checks and a series of certifications are to ultimately lead to official acceptance via the US chief of naval operations, US European Command, and NATO, so the timeline for the Aegis Ashore's actual operation is unclear, he said.

Northrop Grumman has declared the development of its Hatchet miniature precision strike munition ‘finalised' following a series of end-to-end live all-up round (AUR) tests at an undisclosed US government test range on 11 May.

During the US Department of Defense (DoD)-sponsored live-fire event, multiple Hatchet AURs were released from an undisclosed Group 3 tactical unmanned aircraft system (TUAS) against a static target, simulated by an ISO container. The tests involved both point-detonated engagements and proximity initiations.

“These were the first Hatchet release demonstrations using a live warhead,” a Northrop Grumman spokesperson told Janes. “The purpose of the tests was to evaluate the capability of live AURs delivered from a tactical platform. The multiple drops proved 100% reliable for the warhead function, with an ISO container ‘target' utilised to enable our engineers to evaluate the pattern of fragmentation from a live release. Hatchet is designed for precision strike engagements of two metres or less, and this was also verified in each of the releases.”

A representative of Saab Dynamics briefed Janes on its upcoming developments for its shoulder-launched recoilless weapons, revealing details of the HE 448 round that is specifically designed to work in conjunction with the Carl Gustaf M4.

The projectile's warhead consists of a high-explosive (HE) fill and a liner containing 4,000 tungsten balls, each 2 mm in diameter, to defeat body armour. It has a modular fuze capable of both impact and airburst detonations. When programmed for airburst mode, the round is aimed to fly roughly 4 m over the target, with the downward-facing pattern of the tungsten balls capable of covering 400 m2.
