Electro Optic Systems Holdings (ASX:EOS) said it has secured a AU$7 million order with L3Harris in the US for integration into a counter-drone weapon system, with the product to be manufactured in Australia and the order expected to be fulfilled during 2026, according to a Monday Australian bourse filing.

The company said ongoing conflicts in the Middle East and Europe have kept enquiry levels for EOS products elevated, including for remote weapon systems (RWS) and high energy laser weapons.

The company said it expects full-year 2026 revenue for its base business, excluding the newly acquired MARSS business, to be in the range of AU$240 million to AU$270 million, with the timing of revenue recognition of MARSS contracts still being assessed and a further update expected within about two months.

Electro Optic Systems will this week conduct a market launch of the combined EOS and MARSS business at the Eurosatory Defence and Security Exhibition in Paris, it added.

The company's shares fell almost 3% in recent Monday trade.
