Description
Description — SMALL DIAMETER BOMB II
GBU-53/B: Small Diameter Bomb Increment II (SDB II) StormBreaker is a joint interest United States Air Force (USAF) and Department of Navy (DoN) ACAT IC program, with the USAF as the lead service. SDB II addresses the following war-fighter requirements: attack moving and stationary targets, adverse weather operations, multiple kills per pass, multiple ordnance carriage, precision munitions capability, reduced munitions footprint, increased weapons effectiveness, minimized potential for collateral damage, reduced susceptibility of munitions to countermeasures, and provides a network-enabled weapon capability via Link-16 and Ultra High Frequency (UHF) weapon data link. The threshold aircraft for the USAF is the F-15E, and the threshold aircraft for the DoN are the F-35B and F-35C. Objective aircraft include the F-22, F-16, F-35A, B-2, A-10, MQ-9, B-1, B-52, AC-130 and the F/A-18E/F. SDB II is compatible with the Bomb Rack Unit-61 (BRU-61) miniature munitions carriage, Bomb Rack Unit-55 (BRU-55), Type II carriage systems, the CNU-660/E carriage system, the Common Munitions Built In Test (BIT)/Reprogramming Equipment (CMBRE), and the Joint Mission Planning System (JMPS). SDB II employs a single weapon storage container (USAF) and a dual weapon storage container (DoN). SDB II is a key component of the Air Force Global Strike Task Force Concept of Operations (CONOPs). SDB II completed a competitive Risk Reduction in October 2009 and entered Milestone B Engineering and Manufacturing Development (EMD) in August 2010. A Fixed Price Incentive - Firm Target (FPIF) EMD contract with five options for annual (FY 2015-FY 2019) Low Rate Initial Production (LRIP) lots was awarded in August 2010. SDB II received Milestone C approval to enter LRIP in June 2015 and completed an Acquisition Program Baseline (APB) update. Contract options for LRIP Lots 1-5 have been exercised, along with sole source production for LRIP Lots 6-10. Initial Operational Test and Evaluation (IOT&E) started June 2018 and completed May 2019. SDB II was fielded for F-15E in September 2020. The SDB II program has an approved APB dated 12 May 2022 incorporating the new IO and the new F-35B/C integration schedule. SDB II total procurement costs in this document only include USAF weapons, weapon containers, trainers, reliability captive/test vehicles, tactical to guided test vehicle conversions for Air Combat Command's Weapon System Evaluation Program (WSEP), and SDB II product support. Funds may also be used for non-recurring engineering, integration, test, qualification, production readiness, Tech Refresh and operational readiness of engineering change proposals to resolve safety, reliability or other operational deficiencies, decrease weapon system cost, preserve future production capabilities and capacities, and meet Congressional, National Agency and Defense Department mandates. Funding may be used to address Diminishing Manufacturing Sources & Material Shortages (DMSMS) issues. These types of issues may be addressed through bridge buys, life-of-type buys, supplier/parts replacement, and re-qualification. This requirement supports performance of a full financial audit as required by title 10 U.S.C. Chapter 9A, Sec 240-D. Reference BP20 SDB000 for SDB II FY2015-FY2018. SDB II total procurement costs in this document only include 20,334 USAF weapons, the remaining 1,276 USAF weapons were procured in BP20 SDB000. Funding for this exhibit contained in PE 0207327F. NOTE: Tranche funding was received via FY 2025 reprogramming action that is not included in the FY 2025 Enacted Amount contained in the above FY26PB P-40 Resource Summary table: • Ukraine Tranche 28: 85.1M that has been obligated on the Lot 11 buy (1,250 AURs) *As noted, Tranche 28 funding will not be part of any 26PB Procurement (3020) exhibits. *

Related awards
Award linkage is shown for 32 of 200 profiled companies — high- and medium-confidence USAspending matches, each row labeled; medium is the weaker evidence. why partial award coverage? →
Rows marked medium rest on evidence weaker than a program-level match, and of more than one kind. An account-based row, where the award drew from the same appropriation account as this program, is an association, not evidence that this program paid for the contract. Where the evidence is instead an FPDS acquisition-program tag or a subaward description, the program is established but which of its budget lines paid is not. An announcement link a recorded review did not leave standing is medium too. Only high rows rest on the contract naming this program with a recorded review upholding it and no recorded rejection or refutation applying.

Contractor concentration
No concentration index is published for this line. This line's high-confidence links do not clear the floor for a published concentration index — at least 3 awards across 2 contractor families holding positive obligations, with positive net linked dollars. An index below that floor is a fact about the sample, not about the market. Whatever further links this line carries are medium-confidence, and what each medium evidence path does and does not establish is set out in the methodology. Both bases are in the downloadable warehouse.
