The Australian Department of Defence (DoD) is assessing the damage done to its fleet of Boeing P-8A Poseidon maritime multimission aircraft (MMA) following “a severe weather event” last year.

A DoD spokesperson told Janes on 13 January that a hailstorm in South Australia had affected an undisclosed number of Poseidons, and that the aircraft are being inspected to determine the extent of the damage.

“As a result of a severe weather event on 28 October 2021, a number of Royal Australian Air Force (RAAF) P-8A Poseidon aircraft based at RAAF Base Edinburgh incurred impact damage from hailstones. A detailed and comprehensive inspection programme has been undertaken to assess the damage and implement repairs. [The] RAAF continues to be able to complete operational tasking and has sufficient aircraft to meet readiness requirements,” the DoD said.

While the department did not say how many Poseidons were involved in the incident, Janes

Japan's ATLA progresses railgun project

Japan is developing electromagnetic (EM) railguns to counter emerging threats including hypersonic weapons.

A spokesperson from Japan's Acquisition, Technology & Logistics Agency (ATLA) told Janes on 19 January that a study to develop the capability is expected to accelerate in 2022.

“Since financial year 2016 we have studied the underlying technologies of railguns. In the studies we have worked on increasing launch velocity and establishing material technologies for the rails, which have high current endurance characteristics,” the spokesperson said.

The spokesperson added that ATLA will launch studies of future railguns in 2022. These studies will aim to establish entire technologies necessary for early practical use for missile defence and anti-ship operations. The studies aim to achieve a high rate-of-fire and projectile flight stability for the railguns, said the spokesperson.

Janes has previously reported on a video shared by ATLA in July 2018, which showcased a small-calibre developmental EM railgun along with related support and test equipment.

US Space Force eyes hybrid satcom architecture

Members of the US Space Force's (USSF) combat requirements office are weighing options for the development of a hybrid, space-based satellite communications (satcom) architecture, as the US Air Force's (USAF's) premier research directorate is standing up a similar architecture for extra-terrestrial intelligence, surveillance, and reconnaissance (ISR) operations.

The notion of a hybrid satcom architecture is akin to how cellular data is transmitted during voice and video calls, as well as other means of electronic communication. A cellular signal can ping across any number of cellular provider networks and infrastructure, transmitting on to one network, then leapfrogging across other networks until the data reaches its destination. In terms of satcom, under a hybrid approach, data transmission can be initiated through a network at geosynchronous orbit (GEO), then jump onto a satcom network at medium-Earth orbit (MEO) or low-Earth orbit (LEO) – and potentially back up the orbital satcom chain – until the data transmission reaches the receiver.

The United Kingdom has received “considerable interest” in its fleet of soon-to-be-retired Lockheed Martin C-130J/C-130J-30 Hercules airlifters.

A Ministry of Defence (MoD) spokesperson told Janes on 19 January that the sales campaign being run for the Royal Air Force's (RAF's) one remaining short-bodied C-130J C5 and 13 long-bodied C-130J-30 C4 variant Hercules airlifters has attracted a wide range of potential buyers.

“The situation on C-130J sales is that [the Defence Equipment Sales Authority] DESA continues to lead on a very active sales campaign with considerable interest being expressed by a wide range of interested parties,” the MoD said.
