Gilat's EnduroStream order is not mainly about the $7 million
Gilat reported an April 29 order of more than $7 million for EnduroStream to support the U.S. Department of War through a prime contractor. EnduroStream is a power-amplifier layer in satellite ground infrastructure, so the real test is whether a high-power SSPA product can become repeatable defense backlog.
On April 29, GILAT reported an order of more than $7 million for EnduroStream, a Wavestream SSPA (solid-state power amplifier), to support the U.S. Department of War through a prime contractor. Delivery is expected over 24 months. Against 2025 revenue of $451.7 million, the amount alone does not change the company's profile. The question is whether a new power-amplifier product is entering the defense supply chain and can repeat in future orders.
EnduroStream is not a satellite, modem or antenna. It sits in the amplification layer of satellite ground infrastructure: after a system creates and processes the signal, the power amplifier raises that signal's power before transmission from the ground to the satellite. In gateway applications, meaning large ground stations that connect terrestrial networks to satellite systems, and in high-power field terminals, the amplifier helps determine whether the system can transmit at high power and stay available. That makes the order more than another communications-equipment sale; it is a test of an infrastructure layer defense customers need to work over time.
EnduroStream replaces tube-amplifier technology in a sensitive role
The product is positioned as a replacement for TWTA (traveling-wave tube amplifier), an established category of high-power satellite-communications amplifiers. The business difference is not the acronym. It is maintenance and availability. TWTA is tube-based, while SSPA uses solid-state components. GILAT says EnduroStream delivers the power levels required for mission-critical defense environments, with reliability, operational resilience and lifecycle advantages over traditional TWTA-based solutions.
That is the background the technical shorthand did not explain. A defense customer is not buying an amplifier only for its electrical specification. It is buying fewer interruptions, easier maintenance, the ability to modernize ground infrastructure without giving up transmit power, and an architecture that is easier to maintain over time. If EnduroStream performs that role, the order can open a repeatable defense product category. If not, it remains a good but isolated proof point.
The prime contractor validates use, but not the economics
The end customer is a U.S. government body, but the sale goes through an unnamed prime contractor. Unit price, payment terms, gross margin and system count were not disclosed. The announcement therefore does not allow a clear cash or profitability calculation. It does show that a defense contractor is willing to include EnduroStream in supply to a government customer, which is a more meaningful commercial step than a simple development update.
The distance between initial adoption and economic engine remains wide. More than $7 million over two years can enter backlog and turn gradually into revenue, but it does not prove that the product will sell again, carry high margin, or receive a visible place in backlog reporting. Until the company shows follow-on orders, additional customers, or better disclosure, EnduroStream is a positive product signal rather than a proven quantitative change.
The defense order sequence is still small relative to the group
The EnduroStream order follows several defense announcements in recent months: more than $16 million for DKET terminals for a European Ministry of Defense, $9 million for Israel's Ministry of Defense, and a virtualized SATCOM (satellite communications) modem demonstration with AWS, SES Space & Defense and the WAVE Consortium. The sequence matters more than this single order because it points to more entry points with government customers and integrators.
| Timing | Customer or partner | Size or disclosure type | What it tests |
|---|---|---|---|
| February | European Ministry of Defense | More than $16 million | Transportable DKET terminals |
| February | Israel Ministry of Defense | $9 million | Local defense order |
| March | AWS, SES Space & Defense and WAVE | Virtualized SATCOM modem demonstration | New communications architecture |
| April 29 | U.S. Department of War through a prime contractor | More than $7 million | EnduroStream as a high-power SSPA product |
The sequence is not enough to say the defense business has become an independent growth engine. In 2025 the defense division contributed $100.4 million, about 22% of revenue, and grew 3%. Gross profit rose to $29.7 million and margin improved to 30% from 26%, but growth remained modest. By contrast, the commercial segment grew 81% to $281.4 million, while its gross margin fell to 27% from 48%, mainly because of SBS during initial production periods. EnduroStream matters mainly if it improves growth quality, not just the announcement count.
The next reports need to show backlog, revenue and margin
Three tests will decide whether this remains a product event or becomes a business signal. First, follow-on orders for EnduroStream or similar SSPA products. Second, delivery and revenue recognition across the 24-month window. Third, earnings quality: without gross-margin disclosure or backlog split by product, it is hard to know whether the order improves the company's profile or only adds modest revenue.
At the end of 2025, GILAT had about $431.5 million of remaining performance obligations under contracts longer than one year, and 83% is expected to be recognized as revenue within three years. The company does not break that amount down by EnduroStream, SSPA or defense division. The next disclosure that changes the read would be a repeat order, another customer, or better visibility into the backlog and margin behind the product line.
