PSC 1127

Overview

The Product Service Code (PSC) is a uniform taxonomy the U.S. government uses in contracting systems such as FPDS and SAM to categorize what is being bought, enabling consistent tracking, analysis, and reporting of procurement. The PSC Manual maintained by GSA governs the structure, definitions, and use of these codes. ¹
PSC 1127 — Nuclear Rockets — is a product code within Group 11 (Nuclear Ordnance). Official guidance defines 1127 for nuclear weapons consisting of rocket bodies assembled with nuclear warheads and issued as a single item of supply, including certain peculiar components not classifiable elsewhere. It is distinct from non-nuclear rocket classes in other groups. ¹

What this PSC covers

• Complete nuclear rockets: rocket bodies assembled with nuclear warheads, treated as a single item of supply. ¹
• Peculiar components integral to assembled nuclear rockets when not otherwise classifiable. ¹
• Nuclear ordnance training items and specially designed simulators/mockups that are integral to Group 11 nuclear weapons, when not otherwise classified. ¹
• Procurement actions where the predominant deliverable is a nuclear rocket end item, as determined under FPDS PSC selection rules. ¹
• Packaging, kitting, or issuance of the nuclear rocket as a single supply line item per the class definition. ¹

Type	Code	Descriptor
PSC	1115	Nuclear Warheads and Warhead Sections
PSC	1120	Nuclear Depth Charges
PSC	1130	Conversion Kits, Nuclear Ordnance
PSC	1340	Rockets, Rocket Ammunition and Rocket Components (excludes nuclear rockets)

Descriptors per PSC Manual. ¹

Key exclusions and boundaries

• Excludes rocket motors; these are not classified under 1127. ¹
• Excludes warhead components and nuclear components; those belong under 1115 or 1140 as applicable. ¹
• Excludes rocket components that are classifiable in other Federal Supply Classes (e.g., 1340 for non‑nuclear rockets and components). ¹
• General-purpose case sections, nose cones, and similar structures intended for non‑nuclear payloads or general missile/rocket use fall outside Group 11. ¹

FPDS reporting notes

In FPDS, PSC is recorded in data element 8A and should reflect the predominant product. For nuclear ordnance procurements, select 1127 only when the principal item is a complete nuclear rocket as defined; otherwise choose the more specific Group 11 or other PSC that best matches the predominant deliverable. ¹

Frequently asked questions

• What does PSC 1127 include?
  PSC 1127 covers nuclear weapons consisting of rocket bodies assembled with nuclear warheads, issued as a single item of supply. It also includes components peculiar to assembled nuclear rockets when those components are not otherwise classifiable. ¹

• How is PSC 1127 different from PSC 1340?
  PSC 1127 is for nuclear rockets (rocket plus nuclear warhead as one item). PSC 1340 covers rockets, rocket ammunition, and rocket components, but explicitly excludes nuclear rockets and nuclear warheads. ¹

• Are rocket motors coded under PSC 1127?
  No. Rocket motors are excluded from PSC 1127. Classify motors and other rocket propulsion items under the appropriate non‑nuclear PSC based on the manual’s class definitions. ¹

• Does PSC 1127 cover training or inert items?
  Group 11 notes indicate nuclear ordnance training weapons and specially designed simulators/mockups are included when integral and not otherwise classifiable; apply 1127 only if they correspond to the nuclear rocket class. Otherwise select the specific Group 11 class that fits. ¹

• Which NAICS codes typically pair with PSC 1127?
  Not specified by official sources. ²
