Oshkosh nabs $911M for JLTVs for U.S., Lithuania, Brazil, Macedonia
By
Christen McCurdy
Dec. 1 (UPI) -- Oshkosh Defense inked two deals $911 million this week to deliver Joint Light Tactical Vehicles to the U.S. and overseas partners.
On Tuesday, the defense contractor announced that U.S. Army Contracting Command had placed an order for 2,738 JLTVs for the U.S. Army, U.S. Navy, U.S. Marine Corps and U.S. Air Force, "along with a select group of NATO and non-NATO allies."
The Pentagon also announced the domestic sale on Monday night. Under the deal, valued at $888.4 million, Oshkosh is contracted to deliver 2,679 JLTVs, 1,001 trailers and 6,725 kits to the four branches of the U.S. military, with a completion date of Oct. 31, 2022.
Oshkosh also inked a $23 million deal this week to provide 59 vehicles to Brazil, Lithuania and North Macedonia.
"The men and women of Oshkosh Defense take great pride in what they do," said George Mansfield, Vice President and General Manager of Joint Programs for Oshkosh Defense.
"Designing, building, and delivering the world's most capable light tactical vehicle, the Oshkosh JLTV, is one of our greatest accomplishments. And we plan to continue building the Oshkosh JLTV for many years to come," Mansfield said.
This week's deals follow several lucrative awards for the vehicles -- which were developed by the Marines and the Army as a replacement for Humvee -- in the past calendar year.
This week's deals come nearly a year after Oshkosh was awarded an $803.9 million contract to provide JLTVs to the U.S. military and military of Montenegro.
In July, the U.S. Army Contracting Command ordered the construction of 248 Joint Light Tactical Vehicles by Oshkosh, a deal worth $127.7 million, and in February Oshkosh was awarded a $407.3 million contract modification to procure joint light tactical vehicles for the Army.

CH-53E Heavy Lift Helicopter Reaches One Million Flight Hours
Aircraft First Entered Service With The USMC In 1981 The CH-53E Super Stallion helicopter reached a major milestone this year by logging more than one million flight hours since it first entered service with the Marine Corps in 1981. The CH-53E is a versatile machine used for amphibious assault and long-range insertion, delivering troops, vehicles and supplies. This rapid resupply vehicle is still one of the most used aircraft in the United States military air arsenal. “The CH-53E has seen more work than was ever anticipated it would see,” said Major Matthew Baumann, H-53 In-Service, Naval Air Systems Command Heavy Lift Helicopter program office (PMA-261) co-lead. Currently, there are 142 CH-53E Super Stallions in service. Though out of production, the CH-53E is in the middle of a “RESET” – a rolling period of rebuilding, upgrading and increasing safety, reliability and capabilities to lengthen its service life through 2032. According to Baumann, the first 25 helicopters have completed their RESET process, “allowing the squadron commanders to plan for training, operations and maintenance with renewed confidence,” he said. Resetting of the CH-53E fleet is an important segue from the current platform to the new CH-53K King Stallion, which will be its heavy-lift replacement. “The CH-53K is the most powerful helicopter ever built by the United States military,” said Colonel Perrin, PMA-261 program manager. “It will be safer, faster and more capable than any previous heavy lift helicopter in the battlespace.” Its development is currently in the testing and capability requirements phase, with a goal of bringing the CH-53K to fleet Marines by 2024. “It's a game-changer,” said Perrin. “We can't wait to have the K available for fleet use. But for now we've got a capable, reliable and safe helicopter doing heavy-lift for our Marines.” http://www.aero-news.net/index.cfm?do=main.textpost&id=8e63f37f-9874-4fb9-acf1-72e67d6a9cbd

The Pentagon wants help for its satellites to talk to each other
By: Nathan Strout The Space Development Agency wants its satellites to be able to easily talk to each other and is considering using optical intersatellite links for communications within its future low earth orbit space architecture. Now, the organization is looking for industry's help on what standards should be used for those links. On Jan. 15, the agency issued a request for information to industry to inform its attempt to establish an Optical Intersatellite Link Open Standard. Most satellites don't speak with each other directly. Instead, they utilize radio-frequency communications with a ground station to relay communications between satellites. Some satellites, however, are able to use optical links to provide direct communications between satellites without a ground station acting as an intermediary. The SDA wants to use this technology for what it calls its “transport layer,” the backbone of its plans for a new space architecture in low earth orbit. The SDA was established in March 2019 to design the Department of Defense's future threat-driven space architecture, a setup it has since defined as a multi-layered constellation of hundreds of small satellites providing several capabilities from LEO. The SDA will not be directly responsible for every layer or constellation within the architecture — most notably, the Hypersonic and Ballistic Tracking Space Sensor is being developed primarily by the Missile Defense Agency — however, the SDA will be the agency in charge of integrating those various efforts into a single architecture. Key to the entire enterprise is the Tracking Layer, a family of satellites in low earth orbit that will facilitate the flow of data between satellites in orbit and between satellites and the ground. The Transport Layer will be essential in connecting the various sensors and capabilities on orbit with weapons systems on the ground or in the air. In order to build that capability, the SDA plans to use Optical Intersatellite Links. The optical links will also need to provide range estimates of the distance between satellites in orbit and between satellites and the ground to within a meter in order to provide highly precise timing and positional data for the constellation. The SDA also envisions each satellite utilizing a chip-scale atomic clock as well as GPS signals. The problem is that there are currently no industry standards for those links. To ensure the interoperability of various vendor technologies used for those links, the SDA wants to establish that standard, and it's asking industry for help. Responses are due by Feb. 5. More specifics about what the SDA is considering for its standards is available on beta.sam.gov. According to the request, the SDA plans to issue a solicitation for Tranche 0 of the Transportation Layer in Spring 2020, with additional solicitations for the other capability layers to follow in the summer. That first tranche, known as the war fighter immersion tranche, will consist “of tens of satellites providing periodic, regional sensing and data transport capabilities, including the capability to detect hypersonic glide vehicles and to disseminate time sensitive targeting solutions over tactical data links.” According to the agency, that initial tranche could be delivered as early as fiscal year 2022 https://www.c4isrnet.com/battlefield-tech/c2-comms/2020/01/16/the-pentagon-wants-help-for-its-satellites-to-talk-to-each-other/
