Algo más sobre el programa MELT (Modular Efficient Laser Technology): https://sam.gov/opp/11dc6b43a8ef4723ae5 ... 37c99/view

Unos $60 millones durante cinco años. El programa está pensado para la defensa contra drones de bajo coste y enjambres. La novedad es que está hecho de módulos, por lo que la idea es poder escalar fácilmente en función de la demanda de potencia, al mismo tiempo que mantiene una gran precisión: https://sam.gov/api/prod/opps/v3/opport ... ad?&token=
...
A. Background
The proliferation of small, low-cost Unmanned Aircraft Systems (UAS) on the battlefield requires a layered defense that includes low-cost Directed Energy. The deep magazines of Laser Weapon Systems (LWS) are ideally suited to counter swarms of hostile UAS. A variety of other compelling Service LWS applications have been identified, particularly since LWS have the potential to achieve very low operational cost assuming low production costs can be achieved. The market for counter UAS and other applications encompasses HEL sources with a broad range of power levels from a few kilowatts to megawatts. Today, however, each new LWS demands a high level of design and engineering.

B. Program Description
MELT seeks to develop a laser tile as the building block for compact, scalable, panelized HEL sources. It is envisioned that the laser tiles will be integrated into planar arrays for scalable HEL sources with comparable or better performance than current HEL sources. By program end, MELT seeks to demonstrate a 3x3 panelized array of laser tiles with excellent beam quality (BQ) as a scalable HEL source.

The mass, volume, and size goals for the laser tiles and panelized array of laser tiles include the semiconductor amplifier emitters, optics, phase sensing and control, power delivery/conversion, thermal dissipation, computing, external connections, inter-tile electrical, coolant, and data connections. Excluded from the mass, volume, and size goals are the seed laser, chiller, backplane for array of tiles, and electrical and coolant leads leading to the array of tiles.

There are at least two different laser diode technologies that can generate high optical power with excellent beam quality: (1) vertical-cavity surface-emitting laser (VCSEL) diodes, and (2) edge emitting laser diodes. Both technologies are limited to watt-class output power per emitter and therefore a large number of emitters need to be combined to realize a high energy laser weapon system. The challenge in adapting these emitter technologies to directed energy applications is maintaining excellent beam quality while scaling power, which requires coherent beam combining (CBC) of the multiple individual emitters.

El programa ACE ("Air Combat Evolution") entra en su fase 2: https://sam.gov/opp/a663ea810a3e4386ac3 ... ccbd5/view

Del documento asociado: https://sam.gov/api/prod/opps/v3/opport ... ad?&token=
...
The ACE program effort comprises four technical areas (TAs). This solicitation is for TA4. It is expected that coordination with the TA1 and TA2 performers as well as the Experimentation Integration Team (EIT) will be required to achieve performance objectives. A description of each relevant technical area and the EIT follows the figure.

Figure 1 shows the relationship between the different ACE program Technical Areas. The ACE program is constructed to address four primary technical challenges:

1. Technical Area 1: Build combat autonomy for local (individual and team tactical) behaviors
2. Technical Area 2: Build and calibrate trust in air combat local behaviors
3. Technical Area 3: Scale performance/trust to global (heterogeneous multi-aircraft) behavior
4. Technical Area 4: :arrow: Build full-scale air combat experimentation infrastructure
...
After a successful Phase 1, the ACE program has entered Phase 2. As such, this solicitation is for TA4 Phase 2 (Base Period) and TA4 Phase 3 (Option 1). The solicitation also includes an additional aircraft hardware option (Option 2), and an additional aircraft mission systems software integration option (Option 3). The purpose of the Phase 2 and Phase 3 efforts are to support :arrow: autonomous WVR maneuvering and trust research in the ACE program, while the additional aircraft options are designed to support ACE as well as a wider range of autonomy development needs.
...
3. Program Objectives

The primary objective of TA4 is to develop full-scale aircraft experimentation platforms capable of implementing the ACE algorithms and technologies, including human machine interfaces (HMIs), generated by the ACE TA1 and TA2 performers. The TA4 performer will be responsible for full-scale aircraft modification, providing airworthiness documentation, and testing that includes aircraft interface development, ground test, flight test and experimentation, as well as any specialized maintenance. For the Phase 2 Base Period and the Phase 3 Option (Option 1), the performer will modify :arrow: two F-16D aircraft making them capable of integrating WVR autonomy algorithms developed in TA1 and TA2 through an interface specified in a Government-controlled ICD. The performer will also modify aircraft to provide appropriate interfaces for the integration of HMIs developed in TA1 and TA2, safety pilot overrides, and a paddle off/on disconnect capability. The performer will facilitate safety and airworthiness reviews to enable supervised, live WVR engagements.

A secondary objective of TA4 is to establish human-on-the-loop experimentation infrastructure needed to accelerate development of autonomous systems. The hardware and software solutions proposed under the additional aircraft hardware option (Option 2) and the additional aircraft mission systems software integration option (Option 3) are expected to establish the desired human-on-the-loop experimentation infrastructure. In human-on-the-loop experimentation, a pilot sits in the seat of the aircraft with access to all the onboard controls and safety overrides, while the autonomy is given aircraft and mission systems control to test new functionality. A pilot is then able to test an autonomy solution in a real-world setting while being able to disengage the autonomy at any time by “paddling” it off and taking over control of the aircraft and mission systems. This allows the pilot to both provide feedback to developers and to act as a safety net or runtime assurance for the autonomy. It is also desirable for the pilot to be able to “paddle” the autonomy back on to seamlessly re-engage after the pilot makes an adjustment or correction. Modifications to government furnished F-16C aircraft in quantities of 2, 4, 6, 8, or 10 aircraft are requested for the additional aircraft hardware option (Option 2), while the additional aircraft mission systems software integration option (Option 3) is expected to apply equally across all modified aircraft with connectivity to the specified mission system. The first two additional aircraft are desired for ACE 2v2 testing.
...
B. Program Structure and Technical Approach
1. Phase 2 (Base Period - 15 Months)

During the Phase 2 base period the performer will provide the design of a technical solution, perform fabrication, installation, and testing of kits to convert two government furnished F-16D aircraft into human-on-the-loop, safety-sandboxed testbed aircraft which meet the desired attributes of the technical approach outlined in Section I.C, Technical Objectives for Phase 2, Phase 3 and the Additional Aircraft Options.
...
Imagen
...
2. Phase 3 (Option 1 – 15 Months)

The Phase 3 Option period will consist of flight test support of the converted aircraft. At the beginning of Phase 3 the performer will support flight checkout of the two modified F-16D aircraft.
...
3. Additional Aircraft Hardware Option (Option 2 – Notionally 21 months)

The additional aircraft options will convert USAF F-16C aircraft (GFE) that have been equipped with the APG-83 radar into human-on-the-loop, safety-sandboxed testbed aircraft to support autonomy development and experimentation. The additional aircraft hardware option will consist of NRE design, kit fabrication, and kit installation. Required reviews/meetings are a kickoff, a Preliminary Design Review (PDR), a Critical Design Review (CDR), and Test Readiness Reviews (TRR) prior to ground or flight test events. Major review descriptions and expectations are included in Section I.F.

At a high-level, this option will replicate the modifications that were made to the first two F-16D aircraft but on F-16C aircraft, and will add additional hardware connectivity by integrating the mission computer with additional mission systems at the physical layer. This option is only for the physical layer and will not require the performer to modify software to create interfaces at the logical layer. The performer will design and perform physical integration (power and appropriate cabling for data) for the following mission systems in a manner that enables software modifications for paddle-on/paddle-off autonomous control over these systems for human-onthe-loop autonomy experimentation. While software modification is not a part of this option, a high level description of how paddle-on/paddle-off autonomous control could be achieved given the wiring solution is required:

· Northrop Grumman APG-83 Active Electronically Scanned Array (AESA) fire control radar
· Lockheed Martin Legion Pod
· ALQ-213
· Angry Kitten Pod
· Link-16
· Targeting pods such as the Lockheed Martin Sniper pod or the Northrup Grumman LITENING pod

Figure 3 shows a notional system architecture for the additional aircraft option.

...
4. Additional Aircraft Mission Systems Software Integration Option (Option 3)

The additional aircraft mission systems software integration option covers software integration of mission systems with the mission computer. Specifically, the ability to read data from and send commands to the following mission systems (assumes hardware connections are in place from Option 2):

· Northrop Grumman APG-83 Active Electronically Scanned Array (AESA) fire control radar
· Lockheed Martin Legion Pod
· ALQ-213
· Angry Kitten Pod
· Link-16
· Targeting pods such as the Lockheed Martin Sniper pod or the Northrup Grumman LITENING pod

Sobre el "Glide Breaker Phase 2", un estudio de interceptor lanzado desde un VLS pensado para contrarrestar planeadores hipersónicos: https://sam.gov/api/prod/opps/v3/opport ... ad?&token=
...
Glide Breaker intends to advance the United States’ means to counter hypersonic vehicles by enabling intercept of hypersonic threats in glide phase utilizing an interceptor launched from an Aegis MK-41 Vertical Launch System (VLS). In particular, the focus of Glide Breaker is on enabling a divert and attitude control system (DACS) propelled KV capable of intercepting hypersonic threats during glide phase. In Phase 1 of the Glide Breaker program, two DACS prototypes capable of achieving the desired performance objectives were designed and are being fabricated and demonstrated. Testing in Phase 1 includes component tests and static hot-fire demonstrations of the integrated DACS prototypes. Performance in Phase 1 of the Glide Breaker program is not a prerequisite for proposing to this BAA.

Phase 1 was a critical step, but did not address endoatmospheric effects such as controlling the KV in the presence of JI between the DACS jets and the hypersonic cross flow. JI in this regime is complex and dependent on a large number of factors. The Advanced Interceptor Technology (AIT) program in the 1990’s was one of the few projects that have gathered data in this regime. AIT showed that JI effects are highly dependent on outer mold line geometry (including nosecone angle), jet placement, jet geometry, jet thrust, and chemistry effects resulting from unburned propellant reacting with the crossflow. :arrow: Glide Breaker Phase 2 seeks to develop the knowledge required to enable a DACS-propelled KV to intercept threats during glide phase in the presence of JI effects. If successful, the results of Phase 2 will provide the foundation for a future program of record interceptor.

Algo sobre el programa ANSR ("Assured Neuro Symbolic Learning and Reasoning"): https://sam.gov/opp/0c28fb55fcb446dc95e ... 5b36c/view
...
Description

The overarching goal of the ANSR program is to advance hybrid AI algorithms, and develop evidence-based techniques that support confident assurance judgments for these algorithms. The program intends to explore diverse hybrid architectures that can be seeded with prior knowledge, acquire both statistical and symbolic knowledge through learning, and adapt learned representations. The program intends to demonstrate and evaluate hybrid AI techniques through DoD mission relevant use-cases where assurance and autonomy are mission critical.
...

Más información en el pdf asociado: https://sam.gov/api/prod/opps/v3/opport ... ad?&token=
...
The development in the program will be orchestrated in four technical areas (TAs) summarized below:

TA1. Algorithms and Architecture – The goal of TA1 is to develop and model new AI algorithms and architectures that deeply integrate symbolic reasoning with data-driven machine learning. TA1 will explore and evaluate a range of possible algorithms and architecture patterns that are suitable for different tasks.

TA2. Specification and Assurance – The goal of TA2 is to develop an assurance framework and methods for deriving and integrating evidence of correctness and quantifying mission-specific risks. TA2 will establish a pipeline that abstracts the hybrid neuro-symbolic representations into formally analyzable representations and analyzes them with respect to a set of mission-dependent specifications. TA2 will also explore techniques to estimate and quantify mission-specific risks.

TA3. Platforms and Capability Demonstration – The goal of TA3 is to develop use-cases and an architecture for engineering mission-relevant applications of hybrid AI algorithms suitable for the demonstration and evaluation of robust and assured performance. Specifically, the program intends to pursue demonstration through assured execution of an unaided ISR mission to develop a Common Operating Picture (COP) of a highly dynamic dense urban environment.

TA4. Assurance Assays and Evaluation – The goal of TA4 is to 1) develop an assurance test harness with adversarial AI; and 2) evaluate the technologies in individual technical areas and their compositions in systems. TA4 will act as a red team that probes the validity of assurance claims through adversarial evaluations. TA4 will also refine the proposed program metrics and define measures to characterize the trustworthiness of the system. TA4 will need to assess robustness, generalizability, and assurance claims through adversarial evaluation that employs confounding perturbations and quantify the loss of system performance.

G. Intellectual Property

The program will emphasize creating and leveraging open source technology and architectures. Intellectual property rights asserted by proposers are strongly encouraged to be aligned with open source regimes.

A key goal of the program is to establish an open architecture and algorithms that allow for integrating symbolic knowledge and domain-specific representations with data-driven machine learning. This goal includes the ability to easily add, remove, substitute, and modify the type of symbolic representation as well the type of data. This capability will facilitate rapid innovation by providing a base for future users or developers of program technologies and deliverables to build upon and rapidly customize and reuse for different AI applications in both DoD and nonDoD use-cases. Therefore, it is desired that :arrow: all noncommercial software (including source code), software documentation, hardware designs and documentation, and technical data generated under the program be provided as deliverables to the Government, with a minimum of Government Purpose Rights (GPR), as lesser rights may adversely impact the lifecycle costs of affected items, components, or processes.

El programa comenzó en 2020: https://sam.gov/opp/fdf0cf0c62a94f96ba8 ... d324f/view
...
The DARPA JAWS program seeks to develop a software suite to maximize the effectiveness of military force through theater scale battle management command and control with automation and predictive analytics. Sensors, weapons, and decision makers are not assumed to be colocated, and this program considers dynamic coordination of kill webs across the battlespace. This approach to battle management command and control enables flexibility during execution by empowering decision makers to optimize tasking assignments. The goal of this program is to develop the enabling software for the warfighter to adaptably setup and execute synchronized kill webs encompassing the undersea, sea surface, land, air, space, and electromagnetic domains.

The foundational issues for command and control are sensing, communications, and weapons. For the purpose of JAWS, sensing is the ability to detect, geolocate, and identify/classify potential targets sufficiently to engage a weapon, which will vary parametrically by domain and target type. Communications in this context is the ability to ensure the appropriate quantity of data can be passed at the right time and latency in order to coordinate the functions necessary to deploy, maintain, and maneuver assets within the environment. The tasking of weapons is the assignment of weapons and target for engagement with a focus on coordination between weapon systems (e.g. surface, land, and electromagnetic). Each of these components have geospatial and temporal variations, and their optimization is the critical challenge to be addressed by JAWS. Battle damage assessment restarts the cycle and should be considered within sensing. DARPA anticipates performers using these concepts at a minimum when executing the program. However, other taxonomy approaches could be addressed in proposals provided they encompass dynamic execution of all domain kill chains in a kill web context.

Artículo sobre el programa "Gambit": https://www.sandboxx.us/blog/darpas-new ... echnology/
Alex Hollings | July 26, 2022

Last week, the Defense Advanced Research Projects Agency (DARPA) quietly unveiled a new high-speed missile program called Gambit. The program is meant to leverage a novel method of propulsion that could have far-reaching implications not just in terms of weapons development, but for high-speed aircraft and even in how the Navy’s warships are powered.


This propulsion system, known as a rotation detonation engine (RDE), has the potential to be lighter than existing jet engines while offering a significant boost in power output, range, and fuel efficiency.
...
In theory, a rotating detonation engine promises to be much more efficient than traditional jet engines, potentially providing missile applications a serious boost in range and speed. That could also mean fielding smaller weapons capable of achieving the same speeds and ranges as today’s missiles.
...
The Air Force assessed at the time that improvements to their PDE engine could eventually propel aircraft to speeds beyond Mach 4, and higher if combined with other advanced propulsion systems like scramjets. A rotation detonation engine could be even more effective, but many within the academic and engineering communities questioned whether such an engine could ever actually be built.
...

“The objective of the Gambit program is to develop and demonstrate a novel Rotating Detonation Engine (RDE) propulsion system that enables a mass-producible, low-cost, high-supersonic, long-range weapon for air-to-ground strike in an anti-access/area denial (A2AD) environment.”

The program will be conducted in two 18-month phases. The first will entail competitors completing their preliminary designs with some limited testing, while the second would finalize designs and culminate in full-scale flight tests of an RDE system.
...

En el artículo también apuntan a que podría tener cabida en los postquemadores de los cazabombarderos o incluso en las turbinas que equipan a buques, proporcionando en estos una reducción del 10 % del consumo.

The DRACO program seeks to build a nuclear thermal rocket (NTR) engine and test it on orbit in Fiscal Year 2026 (FY26). This solicitation is for Phase 2 and Phase 3 of the DRACO program, which is anticipated to last approximately three to four years. The objectives of Phase 2 are to complete preliminary and detailed design of a Demonstration System (DS) and to construct and experimentally validate the NTR flight engine to the extent possible. The DS will be built to host an NTR for its full-power, on-orbit flight test, in Phase 3.
