Defence industry supplier Ultra Electronics said its Canada-based Tactical Communication Systems business has been awarded an Indefinite Delivery, Indefinite Quantity (IDIQ) contract worth up to $650m over seven years. The award has been made by the Canadian Commercial Corporation acting on behalf of the US Department of Defense. Under the terms of the deal, Ultra will supply upgraded versions of its High Capacity Line of Sight (HCLOS) radios that form the core of the wideband tactical radio systems used by US armed forces engaged in land operations. The initial contract authorisations under the IDIQ contract are valued at about $48m and include over 400 HCLOS multiband radios for delivery in the first half of 2011. Chief executive Douglas Caster said: "This is an excellent example of Ultra delivering its strategies for growth by winning and expanding its positions on long-term programmes, enhancing its specialist capabilities and broadening the group's customer base." "This win also recognises how Ultra continuously improves its range of well proven products and services through a constant drive for innovation."
