L3Harris, Northrop Grumman to build 28 missile-tracking satellites for U.S. Space Development Agency

L3Harris received a $700 million contract and Northrop Grumman a $617 million deal for the Area Improvement Company’s Monitoring Layer Tranche 1

WASHINGTON — The Area Improvement Company introduced July 18 it chosen L3Harris Applied sciences and Northrop Grumman to every construct 14 missile-tracking satellites for a low Earth orbit constellation often known as the Monitoring Layer. 

L3Harris received a $700 million contract and Northrop Grumman a $617 million deal for the Area Improvement Company’s Monitoring Layer Tranche 1. 

The 28 infrared-sensing satellites might be a part of a worldwide community of eyes within the sky meant to detect and monitor the most recent era of ballistic and hypersonic missiles being developed by nations like Russia and China. 

Talking at a Pentagon information convention, Area Improvement Company Director Derek Tournear mentioned the 28 spacecraft might be launched in batches of seven to polar orbits about 600 miles above Earth. Every airplane of seven satellites might be deployed over totally different areas across the globe. The primary launch is projected in April 2025.

Having a constellation of infrared sensing satellites in low Earth orbit has emerged as a prime precedence for the Pentagon amid considerations that present protection methods won’t be capable of detect low-flying hypersonic missiles.

SDA’s Monitoring Layer satellites ought to be capable of see targets with better constancy than present DoD missile-defense satellites in geostationary orbit 22,000 miles above the equator. Present satellites present world missile warning and detect launches of short-range and intercontinental ballistic missiles, however they weren’t designed to trace superior maneuvering missiles like hypersonic glide automobiles. 

SDA in 2020 ordered the primary eight satellites of the  Monitoring Layer — often known as Tranche 0 — from L3Harris and SpaceX. The primary two Tranche 0 satellites are projected to launch in 2023. 

SDA estimated the complete price of the  Monitoring Layer Tranche 1 might be about $2.5 billion, a price ticket that features the 28 satellites in addition to 4 launches, floor integration and help prices. 

Tournear mentioned seven proposals have been obtained for Monitoring Layer Tranche 1. The 2 successful bids have been chosen based mostly on their schedules, technical benefit and value. 

Each L3Harris and Northrop Grumman received so-called “different transaction agreements” utilized by the Pentagon as options to conventional contracts. These agreements require contractors to staff with nontraditional business distributors. Neither L3Harris nor Northrop has but disclosed its business companions for this contract. 

These  are the second main contracts that L3Harris and Northrop Grumman have received up to now from DoD’s area company. L3Harris bought a contract for 4 Monitoring Layer Tranche 0 satellites and Northrop Grumman received a 42-satellite deal for SDA’s broadband constellation known as Transport Layer Tranche 1.  

The info collected by Monitoring Layer satellites could be despatched through optical hyperlinks to the Transport Layer so if a missile risk is detected, its location and trajectory information may be transmitted securely by area and downlinked to army command facilities.

Each the Monitoring and Transport Layers might be inbuilt increments over a number of years, with new satellites acquired each two years. The subsequent Tranche 2 of the Monitoring Layer is predicted to have 54 satellites. 

“The T1 Monitoring Layer effort is a vital step towards constructing the nationwide protection area structure,” Tournear mentioned. “SDA is assured that collection of the L3 Harris and Northrop Grumman groups gives one of the best total resolution to speed up supply of a low-Earth orbit constellation with wide-field-of-view infrared sensors for a worldwide missile warning and missile monitoring functionality.”
