Northrop Grumman expects to shortly integrate a maritime radar on its Firebird optionally piloted MALE UAV.
Liquid hydrogen tank for ScanEagle 3 undergoes tests
Insitu announced on 21 March that a liquid hydrogen (LH2) flight tank for its ScanEagle 3 UAV has completed initial fill, pressure and vapour generation testing.
The tests were carried out last month in the Hydrogen Properties for Energy Research Lab at Washington State University. They verified performance metrics of the LH2 tank before upcoming flights of ScanEagle 3 equipped with a proton-exchange membrane (PEM) fuel cell power system.
The LH2 tank integration project is part of a larger development effort to compare acoustic and thermal signatures of a small UAV powered with an internal combustion engine versus an all-electric power system, Insitu noted.
Andrew Duggan, managing director of Insitu Pacific, said: ‘Operationally, fuel-cell-powered platforms provide the potential for longer endurance missions, increased power availability for payloads, as well as significant reductions in noise signature.’
According to Insitu, fuel cells support better ISR data collection because PEM fuel cell stack emissions are limited to small amounts of water and trace amounts of dihydrogen.
Thermal and acoustic signatures from fuel cells and electric motors are also lower than traditional internal combustion engines, enabling mission routes closer to targets.

A pair of MQ-9As can no longer be operated and owned by General Atomics for strike and targeting missions in the CENTCOM area of operations.
A US DoD contract has revealed that the UK has agreed to buy an additional MQ-9 Reaper. The thinking behind this may be associated with a need to maintain unmanned operational output ahead of the introduction of the MQ-9B SkyGuardian.
