CIBER, MacAulay-Brown/Gray Research, and MEI Technologies and won the Marshall Space Flight Center (MSFC) contract.[16][17] This contract is valued at approximately US$335 million over five years and covers IT security services; IT planning; telecommunication services; applications and web services; computing and audio visual information services.[16]
  • In 2010, Dynetics teamed up with Marshall Space Flight Center and the Von Braun Center for Science and Innovation (VCSI) to build the FASTSAT.[11]
  • In 2012, Dynetics submitted a proposal to NASA based on affordability, reliability, and performance for the F-1 engine, Main Propulsion System, and Structure risk reduction tasks for a possible SLS contract.[11] Dynetics, with partner Aerojet Rocketdyne, was chosen and charged with the task of testing and manufacturing innovative engine components such as an integrated power pack, the primary rotating machinery of the engine.[18][19]
  • Dynetics is to be a key partner to Aerojet Rocketdyne in the development of the AR1 rocket engine. Under a joint venture agreement, Dynetics is to supply elements of the AR1 engine's main propulsion system, the ignition system, and ground support equipment, along with analysis support to critical engine designs.[20]

Dynetics served as systems integrator for the development of what was then the world's largest precision-guided air-dropped system, the 22,600 lb (10,300 kg) MOAB bomb.[21]

In May 2014, Dynetics announced that they will build up to 18 satellites to orbit Earth, in order to gather more data about the planet for the government and businesses. The company will be partnering with OmniEarth LLC, Harris Corp. and Draper Laboratories for the project.[22] Dynetics also partnered with rocket propulsion company Aerojet Rocketdyne to help design upgrades to NASA's Space Launch System.[23]

In 2016, Dynetics was one of four companies to be awarded a contract by DARPA for an air-recoverable experimental unmanned aerial vehicle. Dynetics was chosen from the four companies to build the aircraft, which became the Dynetics X-61 Gremlins. The first X-61A made its maiden flight in January 2020.[24]

Dynetics Human Landing System

[edit]

Dynetics, working with Sierra Nevada Corporation's Space Systems participated in some early human landing system (HLS) design studies under NASA's HLS Appendix E program. They submitted a proposal to NASA for HLS Appendix H for a concept called the Dynetics Human Landing System (DHLS), which in April 2020 was one of three proposals funded for further design work in a US$253 million in NASA development funding contract during 2020/2021, along with Blue Origin's Integrated Lander Vehicle (US$579 million) and SpaceX' Starship HLS (US$135 million).[25][26][27] At the end of the ten-month program, NASA will evaluate which contractors will be offered contracts for initial demonstration missions and select firms for development and maturation of lunar lander systems.[27]

NASA's Stephen Jurczyk identified the fuel drop tanks and low crew module as innovative strengths, but the propulsion system was a low-maturity risk. They received a management rating of "very good" but a technical rating of "marginal", making the Dynetics proposal the worst-rated project.[28][29][30][31]

Robert Wright of Dynetics reported that the Dynetics team selected methane and LOX as the fuel/oxidizer system for their HLS lander because their studies indicated that this choice offered the best combination of performance and long-term sustainability.[32]

Dynetics has been actively involved in NASA's Artemis program since April 30, 2020, when it was selected as one of three prime contractors—alongside Blue Origin and SpaceX—to develop human landing systems (HLS) capable of transporting astronauts to the lunar surface starting in 2024. The company's Dynetics Human Landing System (DHLS), also known as the ALPACA lander, featured a modular, horizontal design emphasizing reusability, affordability through flight-proven technologies, and compatibility with multiple commercial launch vehicles, including NASA's Space Launch System (SLS). This effort included a crew descent element for lunar touchdown and ascent, a habitat module for surface operations supporting two astronauts for up to 14 days, and docking capabilities with the Orion spacecraft or Lunar Gateway. Following NASA's down-selection to for the Artemis III mission in April 2021, Dynetics shifted focus to sustainable lander technologies under NASA's Option B contracts awarded in September 2021, where it was one of five companies tasked with maturing designs for future reusability and risk reduction. By March 1, 2023, Dynetics completed key hardware demonstrations, validating propulsion systems using and , cryogenic fluid management for long-duration storage, lunar dust mitigation to protect mechanisms, power subsystems, and automated docking interfaces. These tests supported broader goals for sustained lunar presence, though Dynetics' lander was not selected for primary follow-on missions, with awarded a contract in May 2023 for a second HLS provider starting late in the decade. Beyond HLS, Dynetics contributes to core Artemis infrastructure through work on the SLS rocket, including design, testing, manufacturing, and delivery of the Universal Stage Adapter under a base contract led by the company as a subsidiary. Its Hardware Integration Facility in , assembles and tests SLS components, such as adapters interfacing the core stage with upper stages or payloads. Dynetics also supports commercial lunar efforts, serving as propulsion provider for Astrobotic's lander by procuring and integrating Frontier Aerospace engines qualified for lunar environments under contracts.

These efforts underscore Dynetics' role in enabling sustainability through integrated engineering, from to environmental controls, while prioritizing cost-effective, heritage-based solutions over unproven architectures.

Hypersonics and Missile Defense Systems

Dynetics has played a central role in advancing U.S. capabilities, particularly through development of the Common-Hypersonic Glide Body (C-HGB), a maneuverable glide designed to achieve speeds exceeding Mach 5 for both offensive strike and defensive interceptor applications. The C-HGB serves as a reusable warhead compartment integrated with boosters for systems like the Army's (LRHW) and the Navy's (CPS), enabling rapid global strike and potential roles by providing a common platform for hypersonic glide vehicles. In August 2019, Dynetics secured a under the U.S. Army's priority strategic hypersonics program to and deliver residual capabilities by 2023, focusing on integration of glide bodies with launch systems. This effort expanded in December 2021 with a to develop Hypersonic (TPS) , addressing the extreme generated during atmospheric reentry at hypersonic velocities, which can exceed 3,000°F. By July 2023, Dynetics received a $428.3 million modification to produce additional C-HGB over four years, building on prior testing to refine , materials, and guidance for operational deployment. Dynetics' hypersonics work extended to testing infrastructure in October 2022, when it was awarded a to enhance the tempo of U.S. tests, including and for validating vehicle performance under real-world conditions. In November 2024, the company obtained a $670.5 million cost-plus-fixed-fee from the U.S. —running through October 31, 2029—to supply C-HGB units and advanced TPS, incorporating matrix composites and ablative materials to withstand sustained . This supports integration into architectures, where the C-HGB's maneuverability could counter adversarial hypersonic threats by enabling interceptors to match speed and trajectory unpredictability. Complementing glide vehicle efforts, Dynetics contributed to air-breathing hypersonics via a December 2022 $334 million -led contract with the for the Mayhem program, developing scramjet-powered systems capable of sustained Mach 5+ flight without boosters, potentially enhancing by providing responsive, loitering hypersonic assets. These programs underscore Dynetics' expertise in and , derived from its facilities, though challenges like material durability under plasma sheaths and precise control at hypersonic speeds remain ongoing engineering hurdles verified through iterative DoD flight tests.

Electronic Warfare and Intelligence Solutions

Dynetics specializes in electronic warfare (EW) systems and intelligence solutions that enhance U.S. military capabilities against adversarial threats, focusing on emulation, countermeasures, and intelligence validation tools. These offerings support the emulation of foreign signatures for testing U.S. systems, assessments, and the development of electronic countermeasures to disrupt enemy sensors and communications. A cornerstone of Dynetics' intelligence solutions is the Laboratory Intelligence Validated Emulator (LIVE) family of products, which consists of hardware systems designed to precisely replicate foreign radars for laboratory-based testing and evaluation. In June 2020, Dynetics was awarded a sole-source, $356 million, 10-year by the U.S. to produce, sustain, and deliver LIVE , enabling accurate simulation of adversary radar behaviors to assess U.S. electronic warfare effectiveness and inform of foreign weapons systems. The LIVE systems incorporate intelligence community-verified data to ensure high-fidelity replication, supporting Department of Defense efforts to counter evolving radar without relying on live adversary engagements. In the EW domain, Dynetics contributes to adaptive countermeasures that protect U.S. from radar-guided threats. In August 2020, as a subsidiary, Dynetics was tasked with developing software for electronic warfare adaptive radar countermeasures on F/A-18 Super Hornet , enabling real-time jamming and deception techniques to evade enemy detection and targeting. These solutions integrate processing with cyber-secure architectures to bolster platform survivability in contested electromagnetic environments. Dynetics also supports broader intelligence, surveillance, and reconnaissance (ISR) systems, providing hardware and software for threat collection and analysis, often in collaboration with U.S. military branches to address gaps in countering advanced adversary electronic systems. Dynetics' EW and intelligence work extends to integrated platforms like the Enduring Shield system, a mobile ground-based counter-unmanned system (C-UAS) unveiled in 2023, which employs —including potential EW elements such as detection and jamming—to track and neutralize multiple drone threats simultaneously. This aligns with Dynetics' emphasis on scalable, verifiable solutions derived from empirical threat data, prioritizing operational realism over simulated or untested models.

Controversies and Criticisms

Contract Disputes and Protests

In April 2021, Dynetics, operating as Dynetics, Inc.-A Leidos Company, filed a bid protest with the U.S. Government Accountability Office (GAO) challenging NASA's award of the Human Landing System (HLS) contract solely to SpaceX. The $2.89 billion contract, announced on April 16, 2021, was intended to develop a lunar lander for NASA's Artemis program, but NASA cited congressional funding shortfalls—allocating only $850 million initially—as justification for a single award rather than the multiple awards solicited under the program's Option A broad agency announcement. Dynetics argued that NASA violated procurement statutes by failing to amend the solicitation, open discussions, or cancel the competition after recognizing insufficient funds for multiple selections, asserting that proceeding with a sole award prejudiced competitors whose proposals, including Dynetics' technically superior but $8.5 billion bid, were deemed too costly. The denied Dynetics' protest, along with a parallel challenge from , on July 30, 2021, concluding that reasonably exercised its discretion under federal acquisition regulations, as the solicitation explicitly permitted one or more awards and had evaluated proposals consistently without bias toward SpaceX. The decision emphasized that agencies are not required to pursue maximum competition when funding constraints arise post-proposal, and 's cost-technical analysis favored SpaceX's lower-priced, viable option. This protest delayed 's HLS progress by approximately three months, during which work on the awarded contract was suspended. Earlier, in 2018, Dynetics protested the General Services Administration's (GSA) evaluation and award decisions under the $50 billion Alliant 2 governmentwide acquisition contract for IT services. Filed in the U.S. Court of Federal Claims (Case No. 18-481), the challenge alleged that GSA acted arbitrarily and capriciously by improperly re-evaluating proposals and failing to adhere to criteria during the down-select process for the multiple-award indefinite-delivery/indefinite-quantity vehicle. The court denied the protest on May 29, 2018, ruling that GSA's actions were rational, supported by the administrative record, and not in violation of laws, thereby upholding the agency's decisions and allowing awards to proceed to other competitors. This outcome aligned with similar denials of related protests by other offerors, affirming GSA's compliance in a highly competitive . Dynetics encountered a prominent tax dispute with the (IRS) over eligibility for (R&D) tax credits under 26 U.S.C. § 41. In September 2012, the company filed a complaint in the U.S. Court of Federal Claims, seeking refunds totaling approximately $10 million for tax years 2005 through 2008, based on qualified research expenses (QREs) incurred on more than 100 government contracts. Dynetics contended that its engineering and development work, including wages under undefinitized contract actions, constituted its own qualified research rather than government-funded activities, thereby qualifying for the credits. The IRS denied the claims, asserting that the research fell under the "funded research" exclusion of § 41(d)(4)(H), which disqualifies credits for activities where the taxpayer does not bear or retain substantial rights to the results. In a May 2015 opinion, the court granted partial to the government, ruling that Dynetics' work on the disputed contracts was funded by the government, rendering the associated expenses ineligible. The decision emphasized that undefinitized contracts did not alter the funded nature of the research, as Dynetics lacked sufficient risk or rights retention. This outcome denied Dynetics the claimed refunds and highlighted limitations on R&D credits for government contractors performing directed development. On the legal front, Dynetics was involved in a contractual initiated by Rolls-Royce's LibertyWorks division in November 2019. The suit, filed in U.S. for the Southern of , accused Dynetics of breaching a teaming agreement for developing a vehicle-mounted high-energy system under a U.S. Army program. LibertyWorks alleged Dynetics fabricated disputes to withdraw from the partnership after securing independent funding, seeking damages for lost opportunities. The parties reached a confidential settlement in January 2023, resolving all claims without admission of liability by either side. This case underscored risks in defense industry teaming arrangements but did not result in precedential rulings on broader legal issues. No major additional tax evasion allegations or systemic legal challenges, such as widespread or litigation, have been publicly documented against Dynetics prior to or following its 2020 acquisition by . The company's operations as a have primarily exposed it to disputes tied to contract interpretations and funding eligibility rather than criminal or regulatory violations.
