PSC 1270

Overview

The Product Service Code (PSC) system categorizes the goods and services the U.S. government buys, enabling consistent coding in procurement reporting and analysis. PSCs are selected to represent the predominant item or service on an award and are entered in FPDS as part of contract data reporting. The active code set and definitions are maintained in the PSC Manual, which guides inclusion/exclusion decisions for each class. ¹

PSC 1270 — Aircraft Gunnery Fire Control Components — covers components designed specifically for aircraft gunnery fire control. According to the PSC Manual, this class includes aircraft turrets, computers specifically designed for gunnery control, and complete gyro mechanisms; it excludes gun chargers, ammunition boxes, gun heaters, field and link chutes, ammunition boosters, gyro components, and complete fire control systems. The class differentiates aircraft gunnery from bombing and from complete systems, which are coded elsewhere. ²

Coding guidance and boundaries

• Group 12 notes direct classification to 1270 when items are designed specifically for aircraft gunnery fire control; aircraft bombing fire control goes to 1280; complete fire control systems are coded under 1230. ²
• Radar equipment designed specifically for fire control belongs in Group 12 fire control classes (e.g., 1285 for fire control radar equipment except airborne), while airborne general radar classes such as 5841 exclude fire control and are coded separately. ²
• DoD supply assignment rules note that certain fire control classes exclude aircraft-type items, underscoring that aircraft-specific components are handled in classes like 1270 and 1280. ³

Exclusions from PSC 1270

• Not in scope: gun chargers, ammunition boxes, gun heaters, field and link chutes, and ammunition boosters. ²
• Not in scope: gyro components (as distinct from complete gyro mechanisms) and complete fire control systems (which are covered by 1230). ²

Frequently asked questions

• What does PSC 1270 include?

  • PSC 1270 includes aircraft turrets, fire control computers specifically designed for aircraft gunnery, and complete gyro mechanisms used in aircraft gunnery fire control. It covers components, not complete systems, and is distinguished from bombing fire control components and complete fire control systems. ²

• How is PSC 1270 different from PSC 1230?

  • 1270 covers aircraft gunnery fire control components. 1230 is reserved for complete fire control systems; anything less than a full system should be classified in the appropriate Group 12 component class, such as 1270 for aircraft gunnery. ²

• When should 1270 be used instead of 1280?

  • Use 1270 when the item is designed specifically for aircraft gunnery fire control; use 1280 for aircraft bombing fire control components. The Group 12 notes direct coding based on the intended fire control function and the subsystem served. ²

• Does PSC 1270 include fire control radar?

  • Fire control radar equipment is separately classified. For example, fire control radar equipment (except airborne) is 1285. Airborne radar classes such as 5841 exclude fire control, with fire control-specific radar placed in Group 12 fire control classes. ²

• Is there an official NAICS crosswalk for PSC 1270?

  • Not specified by official sources. Agencies typically rely on the PSC Manual for scope and use NAICS for industry classification separately; no authoritative crosswalk for PSC 1270 is published on the official PSC Manual site. ⁴
