PSC 1135

Overview

The Product and Service Code system standardizes how the U.S. federal government classifies what it buys, enabling consistent reporting, analysis, and visibility across procurement systems. PSCs are entered on contract actions in the Federal Procurement Data System (FPDS) and are maintained through the government’s PSC Manual. ¹

PSC 1135 identifies “Fuzing and Firing Devices, Nuclear Ordnance.” The PSC Manual specifies that this class includes fuzes, power supplies, firing sets, x‑units, cables, safing devices, adaption kits, and re‑entry vehicle nuclear‑ordnance arming and fuzing systems—items peculiar to the arming, fuzing, and firing of nuclear weapons or their training/simulator counterparts. ¹

What this PSC covers

• Fuzes designed for nuclear ordnance functions and environments. ¹
• Power supplies dedicated to arming and firing circuits for nuclear weapons. ¹
• Firing sets and x‑units integral to nuclear detonation initiation systems. ¹
• Electrical cables and safing devices peculiar to nuclear ordnance. ¹
• Adaption kits used to integrate fuzing/firing components with nuclear end items. ¹
• Re‑entry vehicle arming and fuzing systems for nuclear payloads. ¹

DoD coordinated acquisition assignment

Within the Department of Defense, the Defense Threat Reduction Agency (DTRA) is assigned coordinated acquisition responsibilities for nuclear‑ordnance commodity classes, including PSC 1135. DTRA’s assignment covers items for which it provides logistics or integrated materiel management in accordance with its charter. ²

Group 11 context and boundaries

The PSC Manual notes that Group 11 includes nuclear‑ordnance training weapons, practice ballistic units, and specially designed simulators/mockups when not classified elsewhere. Components are grouped when peculiar to nuclear applications; items designed for non‑nuclear use are excluded or classified in other groups as appropriate. ¹

Frequently asked questions

• What exactly is covered under PSC 1135?
  PSC 1135 covers fuzing and firing devices for nuclear ordnance, including fuzes, power supplies, firing sets, x‑units, cables, safing devices, adaption kits, and re‑entry vehicle arming/fuzing systems. These items are peculiar to nuclear weapon applications or their training/simulator analogs. ¹

• How does PSC 1135 differ from PSC 1140 and PSC 1145?
  PSC 1135 focuses on arming/fuzing/firing functions. PSC 1140 covers components containing or simulating nuclear active materials (excluding end items), while PSC 1145 covers explosive and pyrotechnic components peculiar to nuclear ordnance. All three reside in PSC Group 11 (Nuclear Ordnance). ¹

• Who holds DoD coordinated acquisition responsibility for PSC 1135 items?
  The Defense Threat Reduction Agency (DTRA) holds coordinated acquisition responsibility for relevant nuclear‑ordnance commodity classes, including PSC 1135. DTRA centrally manages items where it provides logistics or integrated materiel management, consistent with DFARS PGI 208.7006 assignments and its charter. ²

• Are there mandated NAICS codes tied to PSC 1135?
  Not specified by official sources. ³

• Where can authoritative PSC 1135 data be programmatically accessed?
  GSA’s SAM.gov PSC Public API provides active PSC data (codes, names, notes, includes/excludes). You can filter to code 1135 via query parameters and integrate results into procurement analytics, subject to API usage policies and rate limits. ⁴
