        "description": "Project CALLISTO Requirement: Affordable, single use engines for current and future air systems, munitions & One Way systems, to bridge the performance gap between hobbyist, model aircraft engines and higher performance, long-life & more exquisite engines. This phase will consist of design, development and ground testing (in appropriate engine test facilities) of Qty 4 prototype engines. The engines must be affordable and scalable. Any future scaled production requirement is not included under this competition, and if required shall be subject to a separate procurement. LOTS: This procurement is split into TWO Lots: LOT 1 CALLISTO LIGHT is for a smaller, less powerful engine (750N) LOT 2 CALLISTO HEAVY is for a more powerful engine, (1.8-2kN) Tenderers are able to bid for one or both lots. Full details of the requirement and anticipated dates can be found in the linked ITT. Tenderers wishing to take part must submit an ITT on the Defence Sourcing Portal no later than the specified closing date.",
