WASHINGTON — The U.S. Air Force on Wednesday stated its intent to sole source A-29 Super Tucanos from Sierra Nevada Corp. and Embraer. But a similar solicitation for Textron's AT-6 Wolverine will be forthcoming, an Air Force spokeswoman confirmed.
The Air Force intends to put out a final solicitation to the SNC-Embraer team this month and will award a contract by the end of the fiscal year, according to a May 8 notice on FedBizOpps.
“We expect a separate procurement action for the AT-6,” Air Force spokeswoman Ann Stefanek told Defense News. Stefanek added that the service still intends to buy two to three of each aircraft for more experiments at Nellis Air Force Base, Nevada, and with the special operations community at Hurlburt Field, Florida.
Earlier this year, the Air Force acknowledged it was unprepared to move its light-attack experimentation effortinto a full-fledged program of record. Instead, the service kept both options — Textron's AT-6 and the SNC-Embraer A-29 — on the table and requested $35 million to continue testing the jets in fiscal 2020.
Some analysts and lawmakers have accused the Air Force of slow-rolling the program in an attempt to see it quietly canceled, despite congressional enthusiasm for buying new attack planes.
However, Air Force Chief of Staff Gen. Dave Goldfein maintains that future experiments will help the Air Force narrow down light-attack capabilities that the service and foreign nations need. He has also said the service will be ready to make procurement decisions around the FY22-FY24 time frame.
“The United States Marine Corps has already said they're joining us,” Goldfein said in March. “We're going to invite allies and partners, and with the authorities you've given us now that we own those prototypes, we will continue to experiment to build the interoperable network that we've already advanced.”
According to the pre-solicitation, the light-attack aircraft “will provide an affordable, non-developmental aircraft intended to operate globally in the types of Irregular Warfare environments that have characterized combat operations over the past 25 years. Additionally, it will support Air Force Special Operations Command (AFSOC) with the ability to accomplish its mission of Close Combat Air support to partner nations.”
The Air Force has said that funding for the initial AT-6 and A-29 buys will come out of the estimated $160 million in unspent funds that Congress appropriated for the effort in previous budgets. Congress has appropriated $200 million in total for the effort since it was announced in late 2016.

DARPA's SIGMA program, which began in 2014, has demonstrated a city-scale capability for detecting radiological and nuclear threats that is now being operationally deployed. DARPA is building off this work with the SIGMA+ initiative that is focused on providing city- to region-scale detection capabilities across the full chemical, biological, radiological, nuclear, and explosive threat space. DARPA initiated a SIGMA+ pilot study last year known as ChemSIGMA to provide initial data and insights into how new chemical sensors using the existing SIGMA network would function. The chemical sensor package incorporates a chemical sensor, wind sensor and communications board into a weatherproof housing. Sensors report wind readings and real-time chemical information to a central cloud-hosted suite of fusion algorithms. “The algorithms were developed using a custom simulation engine that fuses multiple detector inputs,” said Anne Fischer, program manager in DARPA's Defense Sciences Office. “We built the algorithms based on simulant releases in a large metropolitan area – so we took existing data to build the algorithms for this network framework. With this network, we're able to use just the chemical sensor outputs and wind measurements to look at chemical threat dynamics in real time, how those chemical threats evolve over time, and threat concentration as it might move throughout an area.” In the pilot study, DARPA researchers from MIT Lincoln Laboratory, Physical Sciences Inc., and Two Six Labs, built a small network of chemical sensor packages. In partnership with the Indianapolis Metropolitan Police Department, Indianapolis Motor Speedway, and the Marion County Health Department, DARPA's performer teams deployed the network on-site at the Indianapolis Motor Speedway in late April 2018. The chemical sensor network and the data collected during events such as the 2018 Indianapolis 500 were critical to the DARPA effort, allowing the team to assess the performance of the sensors and network algorithms. These tests were conducted in an urban environment to ensure that the system could handle complex and stochastic signals from species that are ever present in a city's chemical background. Significantly, the network-level algorithm successfully improved system performance by correctly suppressing false detection events at the individual detector level. The group of DARPA researchers was also able to collect a large relevant data set and valuable user feedback that will guide ongoing system development efforts. Further testing with safe simulant/concert smoke at Indianapolis Motor Speedway, August 2018 During additional tests in August 2018, a non-hazardous chemical simulant was released in the empty Indianapolis Motor Speedway at a realistic threat rate. Concert fog was also released to serve as a visible tracer. The propagation of the visible tracer was observed in aerial photography, and ChemSIGMA sensors and algorithms determined the release location with unprecedented accuracy. The web-based ChemSIGMA interface allows the user to view alerts in real time across a variety of devices. Multiple trials were conducted over the course of several days assessing performance over a variety of meteorological conditions. Releases occurred during daytime and nighttime with a full range of wind directions and speeds. The ChemSIGMA prototype system detected all of the simulant releases and generated zero false alarms over the course of testing. Department of Defense simulant testing at Dugway Proving Ground, Utah, October 2018 “We're looking at how we might make this network more robust and more mature,” Fischer said. “For example, we implemented a network at Dugway Proving Ground as part of a DoD test for simulant releases, and have shown that the network can respond to a number of chemical simulant threats different than those used in Indianapolis, as well as built-in capabilities for mobile releases. Over the past few months, the team has used these data sets to further refine the algorithms, and plans to integrate and test them with the ChemSIGMA system in test events scheduled later this year.” The successful pilot and simulant test of the ChemSIGMA system at the Indy500 and Dugway Proving Ground provided valuable, relevant, and realistic data sets for validation and verification of the source localization and plume propagation algorithms. DARPA is currently extending the capabilities for networked chemical detection by advancing additional sensor modalities, including short-range point sensors based on techniques, such as mass spectrometry, and long-range spectroscopic systems. As these systems are further developed and matured, they will be integrated into the SIGMA+ continuous, real-time, and scalable network architecture to increase the system's capabilities for city-scale monitoring of chemical and explosive threats and threat precursors. https://www.darpa.mil/news-events/2019-04-30

By: Valerie Insinna   WASHINGTON — The United States on Thursday approved a planned purchase by Japan of 105 F-35 joint strike fighters, moving the country one step closer to becoming the biggest foreign customer of the Lockheed Martin-produced jet. The approved package includes 63 F-35A conventional takeoff and landing aircraft and 42 F-35 short takeoff and landing variants, essentially green-lighting the procurement plans spelled out by Japan in 2018. The Defense Security Cooperation Agency notified Congress of the possible sale, which is worth about $23 billion, although that number could change during negotiations between the country and Lockheed Martin. Those negotiations would start after Congress approves the sale. Also included in the arms deal is: 110 Pratt & Whitney F135 engines, associated electronic warfare and communications systems, the Autonomic Logistics Information System, training gear, infrared flares, a performance-based logistics package, software integration, spare and repairs parts and other support. If Japan moves forward with the purchase, it would have a total of 147 F-35s — becoming the second-largest operator of the joint strike fighter after the United States and just ahead of the United Kingdom, which plans to buy 138 jets. It would also become the fourth user of the F-35B variant, which is being bought by U.S. Marine Corps, the United Kingdom's Royal Air Force and the Italian Navy. Several other sales were also announced on Thursday: Taiwan: The State Department has approved a request by Taiwan to recertify its Patriot Advanced Capability-3 missiles for an estimated cost of $620 million. The package includes replacing PAC-3 components that are near expiration, test and repair of the capability, spare parts for ground support equipment and other logistics support. According to DSCA, “this proposed sale will help sustain the recipient's missile density and ensure readiness for air operations. The recipient will use this capability as a deterrent to regional threats and to strengthen homeland defense.” Lockheed Martin would be the prime contractor for this sale. Germany: If approved by Congress, Germany would get MK 54 All Up Round Lightweight torpedoes, 10 conversion kits and related equipment in a package worth about $130 million. The deal, which help upgrade Germany's P-3C submarine hunting planes, also includes fuel tanks for the torpedo conversion kits, spare parts, launch accessories for the aircraft and various logistics and program support. Raytheon would be the prime contractor for this purchase. Belgium: The State Department also authorized Belgium's request for 29 All Up Round MK 54 LWT Mod 0 torpedoes. The $33 million package includes two Fleet Exercise Section conversion kits, torpedo support equipment, and logistics support. The approval comes as Belgium phases out MK 46 torpedoes and begins using the MK 54 aboard its NH-90 helicopters and multi-mission frigates.
