Opinion

BLAIR, District Judge.

INTRODUCTION

This is an action on a contract for the sale of goods brought by the buyer (Westinghouse) to recover the amount paid in excess of the contract price to procure the contract goods after the seller (Garrett) allegedly defaulted and consequently was terminated by the buyer. The seller counterclaims, charging that the termination was wrongful and that it may therefore recover its costs. By agreement of the parties the case was bifurcated for separate trials of liability and damages. The case has now been ably tried and briefed at length by counsel for both sides on the issue of liability. The court’s findings and conclusions on that issue follow.

FINDINGS OF FACT

1. The plaintiff, Westinghouse Electric Corporation, is a Pennsylvania, corporation with Aerospace and Electronic Systems Division facilities located at Baltimore, Maryland.

2. The defendant, Garrett Corporation, is a California corporation with its offices in the State of California.

Technical Background

3. An Electronic Counter Measure (ECM) pod is a device attached to combat aircraft to counter enemy radar tracking devices. Its function is to jam or confuse enemy antiaircraft radar defense systems so that those systems “locate” an aircraft at a different (and incorrect) place. By thus deceiving the radar, the ECM pod causes enemy fire reliant on that radar to miss the aircraft.

4. The ECM pod concept has been in use and under further development since the 1950’s through the present date.

5. The electronic equipment used to confuse ground radar (primarily “TWT’s” or “traveling wave tubes”) and the power supplies required to operate such equipment generate large amounts of heat as they function. ECM pods thus require cooling to prevent heat from impairing the operation of the pod electronics. Airborne cooling systems used in ECM pods operate by causing heat from the electronic components to be transferred by conduction to a fluid (the “coolant”). Early ECM pods utilized an “open-loop” system: once the coolant had picked up heat, it was expelled from the pod into the airstream. Using an open-loop” system, therefore, an ECM pod can operate only as long as the reservoirs within the pod contain coolant.

6. The pod program involved in this case was designated “QRC-522.” “QRC” stands for “quick reaction capability” and is a concept peculiar to the electronic warfare aspects of our national defense. QRC programs are designed to permit the Air Force to procure highly complex systems rapidly and to make fast decisions at low management levels in order to counter more quickly new enemy “threats” (for example, new enemy radar).

7. In mid-1972 the nomenclature was changed to “AN/ALQ-119.” “AN” stands for “Army-Navy”; “ALQ” stands for “airborne electronic countermeasure.” AN/ALQ-119, ALQ-119 and QRC-522 are used interchangeably hereinafter.

8. In order to accommodate changes desired by the Air Force to increase the effectiveness of its ECM pods while maintaining size, weight and power restraints, the QRC-522 program required the design of a dual “open-loop” and “closed-loop” cooling system. In a “closed-loop” system, the coolant would not be expelled from the pod after it had been heated, but would itself be cooled by transferring the heat it had absorbed to the airstream. The coolant would then be returned to the system to repeat the cycle.

9. A QRC-522 pod is divided into three cylindrical modules ten inches in diameter and of varying lengths: the Service Module, about 25 inches long, and Modules A and B, which are about 38 and 68 inches long, respectively. Within each module, bisecting the cylinder throughout its entire length, is a component called a “cold plate” assembly, consisting of two individual cold plates and a frame to which they are joined. The cold plates themselves (two for each module, or six for each ECM pod) are made up of many small, finned, aluminum passageways, through which the liquid coolant flows. Electronic components are mounted to the outside of the cold plates, primarily those in the A and B modules. The heat these components generate is conducted through the surface of the cold plates and absorbed by the coolant, which flows through the internal fins under pressure created by a pump attached to the Service Module coldplate assembly.

10. In the closed-loop phase after the coolant (known as Coolanol 20 for the ALQ-119) has absorbed the heat from the electronic components, it passes to the aerodynamic surface heat exchangers (ASHX’s). These ASHX’s are mounted on the outside skin on each side of the A and B modules of the pod. They also contain fins through which the coolanol flows, and additional coolanol flows through a passageway in the outer skin of the ASHX’s. Air flowing past the pod is drawn into the ASHX’s. The heat in the coolanol is transmitted by convection to the passing air, and the now-cooler coolanol returns to the cold plates to absorb more heat from the electronic equipment in a continuous cycle. There are two *1305 ASHX’s on Module A and two on Module B; there are no ASHX’s on the Service Module.

11. Reservoirs, or accumulators, in the coolanol line take care of coolanol volume losses and also, because they are spring loaded, maintain a constant pressure in the line.

12. In the “open-loop” phase of the ALQ-119 cooling system, the space between the two cold plates and within the frame in each module is utilized as a “water boiler.” For limited periods of time and under certain flight, mission, and climatic conditions, the closed-loop system was expected to be unable to provide sufficient cooling capacity. Upon proper automatic triggering by a heat-sensitive diverter valve, the coolanol is diverted from the ASHX’s and flows instead to an enclosed passage that runs through the water contained in the water boilers. This permits the water to absorb the heat, boil at fixed temperature ranges and be expelled through the automatic pressure-reduction devices (sometimes called “steam vents”).

II.

Contractual Background

13. The procurement cycle for the QRC-522 ECM pod began in 1970. 1 Garrett as of that time had many years experience designing and fabricating devices and systems for the temperature conditioning of airborne electronics, including over ten years of general acquaintance with the subject of closed-loop cooling systems. Although Garrett had no significant experience with the design and production of cooling systems for ECM pods, it had early in 1970 made a theoretical study of a closed-loop cooling system under a contract with Westinghouse and submitted a report on February 17, 1970.

14. Westinghouse decided to buy most of the components for the QRC-522, including the cooling system. Although Westinghouse had manufactured in-house the open-loop cooling system for the predecessor pod, it decided to buy rather than make the cooling system for the QRC-522 because it believed it lacked the necessary manufacturing technology, notably the capability to braze the aluminum fins to the cold-plate surfaces.
