Exhibit 99.1

T3 Defense wins $1.3 Million Power-Generation

Order for European Air-Defense Production

Order from a leading Israeli defense prime,

supports a European production line for a critical air-defense system

NEW YORK and NETANYA, Israel, September 10,

2026 -- T3 Defense Inc. (Nasdaq: DFNS) (“T3 Defense” or the “Company”), a defense company that acquires and

operates mission-critical defense businesses involved in national security programs, today announced that its wholly owned subsidiary,

Rimon Agencies Ltd. (“Rimon”), has received a purchase order valued at approximately $1.3 million from a leading

Israeli defense prime contractor. Rimon will supply engineered power-generation systems for a European production line supporting a critical

air-defense system.

The equipment will be built and configured to

the prime contractor’s specifications and the requirements of serial defense production, with deliveries scheduled for the customer’s

European production facility.

This order is the first Rimon purchase order tied

to European air-defense production activity, demonstrating demand for its engineered power-generation systems in a critical defense-production

environment.

“Europe’s continued investment in

layered air defense would create demand for the sub-systems our businesses provide,” said Menny Shalom, Chairman and Chief Executive

Officer of T3 Defense. “This order from a leading Israeli prime contractor is a tangible example of that demand. Rimon has been

selected to supply power-generation systems for a critical air-defense production line in Europe, reinforcing the strategic relevance

of the portfolio we have assembled, and it opens a path for Rimon into the European air-defense supply chain, where we see multi-year,

program-driven demand for exactly this class of hardware.”

“This is a production-line order, not a

one-off delivery, that reflects Rimon’s engineering and manufacturing capabilities and established record supporting Israel’s

most demanding customers,” said Itamar Shimoni, Chief Executive Officer of Rimon. “Power generation is where Rimon started,

and supplying it into a European defense production environment is a significant step in the expansion of our footprint beyond Israel.

We are preparing for the initial delivery phase while continuing to evaluate and invest in building the capacity required to support additional

volume from this customer and others.”

Portfolio Context

T3 Defense continues to position its operating

subsidiaries, including Rimon, Positech, Tiltan, ITS, and Nimbus across the mission-critical hardware and systems used in defense and

counter-drone programs. The Company’s portfolio spans launcher systems, tactical mobility, power generation, positioning and navigation,

command-and-control, and training and simulation capabilities that support the deployment, operation and sustainment of layered defense

architectures.

Rimon’s recent performance reflects growing

demand for its capabilities. As of July 31, 2026, Rimon had generated approximately $5.25 million in year-to-date revenue, already exceeding

its full-year 2025 revenue of $4.6 million. As of the same date, Rimon had approximately $2.1 million in backlog scheduled for delivery

through year-end. The new order has been added to that backlog.

Through its subsidiaries, T3 Defense seeks to

serve defense customers and prime contractors in Israel, Europe and other allied markets, where modernization, readiness and force-protection

requirements are driving demand for these categories of equipment and support.

About Rimon

Rimon is a bespoke engineering and systems integration

company that develops mission-ready infrastructure platforms for defense, homeland security, and emergency response operations. The company

imports, distributes, and upgrades mobile power systems, elevated sensor masts, and builds integrated mission vehicles that support surveillance,

communications, and command systems operating in environments where permanent infrastructure is unavailable. By engineering systems around

real operational requirements, Rimon enables critical technologies to be deployed rapidly and operate reliably in demanding field conditions.

About T3 Defense Inc.

T3 Defense Inc. (Nasdaq: DFNS) is a defense company

that acquires and operates mission-critical defense businesses involved in national security programs. It focuses on manufacturers with

strong customer relationships and solid order backlogs, often capacity- and resource-constrained, in specialized areas such as drones

and autonomous vehicles, counter-drone systems, advanced manufacturing, tactical robotics, and AI software and system integration. Through

disciplined acquisitions, centralized capital and strategy, and decentralized day-to-day operations, T3 Defense aims to strengthen essential

defense capabilities and build long-term value. For more information, visit www.t3dfns.com.
