The high-wing configuration was not only for excellent visibility but also for the protection of engines and critical components from ground debris. The use of a turboprop engine was a strategic choice, providing a balance between performance, reliability, and maintenance simplicity.
Performance was a cornerstone of the CL-760’s design. The aircraft was engineered for Short Takeoff and Landing (STOL) capabilities, which were essential for operations in austere environments and near the front lines.
The choice of a turboprop engine also meant the aircraft would have a significant range and endurance, critical for reconnaissance missions and prolonged loiter times over battlefields. This engine selection also ensured the aircraft had enough power for agile maneuvering, a crucial aspect of close air support missions.
Lockheed’s engineers also faced the challenge of integrating these features into a cohesive design that could be easily produced and maintained.
This was particularly important as the aircraft was intended for widespread use in various theatres of operation. The design had to be not only effective but also cost-effective, both in terms of initial production and long-term maintenance and operation.

In addition to reconnaissance, the CL-760 was also designed for close air support (CAS) roles. Its armament capabilities, which could include machine guns, autocannons, and rockets, allowed it to provide direct and immediate fire support to ground troops engaged in combat.
The aircraft’s agility and STOL capabilities meant it could operate close to the front lines, delivering precise and effective support when and where it was most needed. This direct support role was vital in increasing the survivability and combat effectiveness of ground forces.
Another potential role for the CL-760 was in target acquisition and forward air control. The aircraft could be used to identify enemy targets and direct more powerful, but less agile, strike aircraft to these targets. This role was particularly important in complex battlefields where identifying and hitting high-value targets quickly could turn the tide of an engagement.
The versatility of the CL-760 extended beyond combat roles. Its potential for adaptation to non-combat roles was significant.
The aircraft could be configured for medical evacuation missions, leveraging its STOL capabilities to retrieve wounded soldiers from areas inaccessible to larger aircraft. It could also be used for light cargo transport, delivering essential supplies to forward-deployed units.

The potential of the CL-760 LARA was not limited to conventional warfare scenarios. Its capabilities made it well-suited for counter-insurgency operations, where its ability to provide persistent surveillance and rapid-response support was invaluable.
In such environments, the aircraft’s ability to operate from rudimentary airfields and its low-level flying proficiency were particularly advantageous.
The CL-760 was designed to have short takeoff and landing (STOL) capabilities, allowing it to operate from short and rudimentary airstrips. This feature was critical for forward operating bases and for missions in areas lacking developed airfields. The aircraft’s performance was optimized for low-level operations, a requirement for effective reconnaissance and close air support.
Primary Operational Roles
Reconnaissance
The CL-760 was primarily conceived as a reconnaissance aircraft. Its design allowed for excellent visibility and the inclusion of advanced surveillance equipment. The aircraft’s capability to fly at low altitudes and speeds, coupled with its endurance, made it ideal for gathering detailed intelligence over enemy territories or for border surveillance.

Its ability to operate from short and unprepared runways enhanced its effectiveness in forward-deployed locations, providing real-time intelligence essential for operational planning and decision-making.
Close Air Support (CAS)
Another significant role for the CL-760 was close air support. The aircraft’s potential to carry a variety of weapons, including machine guns, rockets, and light bombs, made it a valuable asset for supporting ground troops in combat.
The agility and responsiveness of the CL-760 would have allowed it to react quickly to changing situations on the battlefield, delivering precise and effective firepower where needed most. Its STOL capabilities further enabled it to operate from forward bases, close to the combat zones.
Secondary and Potential Roles
The CL-760’s design also lent itself to light attack and interdiction missions. While not as heavily armed as dedicated attack aircraft, its speed and maneuverability, combined with a respectable weapons payload, would have made it effective in harassing enemy supply lines, attacking light-armored vehicles, and performing hit-and-run attacks on enemy positions.
Forward Air Control (FAC)
As a Forward Air Controller, the CL-760 could have played a critical role in guiding and coordinating air strikes. Its ability to get close to the action and remain on station for extended periods made it an ideal platform for this role, helping to direct more powerful, but less nimble, aircraft to their targets.
Non-Combat Roles
Beyond combat, the CL-760’s flexibility suggested its utility in non-combat roles such as training, light transport, and search and rescue operations.
