# Source: NASA SLS Booster Contract NNM07AA75C **Type:** source **Status:** Useful **Confidence:** High **Source Type:** government-record **URL:** https://www.usaspending.gov/award/CONT_AWD_NNM07AA75C_8000_-NONE-_-NONE- **Publisher:** USAspending.gov (U.S. Department of the Treasury), from NASA's contract reporting to FPDS **Retrieved:** 2026-08-12 **Updated:** 2026-08-11 ## Summary The federal award record for NASA contract **NNM07AA75C** — the five-segment solid rocket booster contract held by **Northrop Grumman Systems Corporation** and performed in **Corinne, Box Elder County, Utah**. It began as the Ares I first stage under Constellation and is now the Space Launch System booster contract: modifications through 2026 are described in the award's own transaction record as "SPACE LAUNCH SYSTEM (SLS) BOOSTER." This is the record that ties the booster program to a Utah place of performance. Northrop Grumman's Form 10-K names Corinne as a Space Systems location and names the SLS booster program, but never connects the two; this award does, with a street address, a county, and a dollar figure. ## Useful Claims - Award identity: PIID **NNM07AA75C**, a definitive contract (award type D), signed **2007-08-10**, period of performance **2006-04-17** through **2026-12-31**, NAICS **336415** ("Guided Missile and Space Vehicle Propulsion Unit and Propulsion Unit Parts Manufacturing"). - Recipient: **Northrop Grumman Systems Corporation**, UEI **LRVQERN7YNH9**, at **9160 N Hwy 83, Corinne, UT 84307** (Box Elder County). Parent recipient: **Northrop Grumman Corporation**, UEI **NKVZLJL93QT6**. - Place of performance: **Corinne, Box Elder County, Utah**, ZIP 84307, congressional district UT-01. This is a Utah-performed contract, not a Utah-headquartered company's out-of-state work. - Money: **$4,430,784,857** obligated to date, against a base-and-all-options value of **$4,474,280,956** — one of the largest single federal awards performed in Utah. - Scope, from the contract description: development, qualification, certification and acceptance of a first stage that "will be a five segment, solid rocket booster derived from the Space Shuttle Program (SSP) Solid Rocket Booster (SRB)/Reusable Solid Rocket Motor (RSRM)," including five full-scale ground static test motors — two development motors and three qualification motors — plus a structural test article and ground vibration test motors. - The work is current, and it is SLS: the most recent modifications in the award's transaction record are **modification 420, dated 2026-06-30**, each described as "SPACE LAUNCH SYSTEM (SLS) BOOSTER," with obligations still flowing in 2026. - Competition: not competed. Extent competed **C** ("NOT COMPETED"), other-than-full-and-open reason "ONLY ONE SOURCE-OTHER (FAR 6.302-1 OTHER)", one offer received. The award record is therefore also the government's own documentation that it treats this capability as sole-source. ## Verbatim From the award record and its transactions, exactly as the API returns them: ``` piid NNM07AA75C type_description DEFINITIVE CONTRACT date_signed 2007-08-10 period_of_performance 2006-04-17 to 2026-12-31 total_obligation 4430784857.0 base_and_all_options 4474280956.0 recipient_name NORTHROP GRUMMAN SYSTEMS CORPORATION recipient_uei LRVQERN7YNH9 recipient address 9160 N HWY 83, CORINNE, UT 84307-9501, BOX ELDER county parent_recipient_name NORTHROP GRUMMAN CORPORATION parent_recipient_uei NKVZLJL93QT6 place_of_performance CORINNE, UT 84307, BOX ELDER county, congressional district 01 naics 336415 GUIDED MISSILE AND SPACE VEHICLE PROPULSION UNIT AND PROPULSION UNIT PARTS MANUFACTURING major_program ARES I FIRST STAGE extent_competed C NOT COMPETED other_than_full_and_open ONE ONLY ONE SOURCE-OTHER (FAR 6.302-1 OTHER) number_of_offers_received 1 ``` Contract description, verbatim: ``` FIRST DDT AND E, ARES I-X, AND FLIGHT TESTS.

What it does and does not establish. It **does** establish that a multi-billion-dollar NASA solid-rocket-booster contract is performed at a Box Elder County address by Northrop Grumman Systems Corporation, and that the current work is SLS booster work. It **does not** establish anything about the motor's dimensions, thrust, or test history, nor about site employment: federal award records carry money, dates, places, and codes, not engineering specifications. The site name "Promontory" appears nowhere in the record; the tie is the Corinne mailing address, which the company also reports to the SEC as a Space Systems location. Two data cautions. The contract **description is the original 2006 Ares I scope** and was never rewritten when the program became SLS — which is why the description and the recent modification titles disagree, and why the transaction record rather than the description is what dates the work. And obligations are cumulative across two decades and many modifications, so the total is not an annual figure; USAspending's outlay figures on older awards are also incomplete, because linkage to federal-account outlays only began part-way through this contract's life.
