Munition Drones

Precision Carbon Tubes for Tactical Drone Payloads

Request a technical consultation

Engineered for repeatable production at scale, C-Tech manufactures ultralight, high-strength carbon fibre tubes engineered specifically for expendable loitering munitions and tactical drone applications. Using prepreg carbon layups on precision-ground mandrels, we ensure structural consistency, superior tensile strength, and aerodynamic performance — critical for payload stability and mid-flight resilience.

Our tubes can be tailored for specific mission profiles including launch tube housings, guidance structures, and fuselage bodies. All components are manufactured with tight tolerances and repeatable mechanical properties, supporting high-speed production and deployment.

Battens & Hardware

Trusted by leading sail lofts worldwide. We’ve spent decades refining sail performance with the most durable and reliable hardware in the business.

SlickJS Slider Instructions

Step 1: Add head and body code to page settings.
In the Navigator, find the embedded code blocksHead Code (Delete After Copying) and Body Code (Delete After Copying)

Open the Head Code (Delete After Copying) embed, copy the code and place it in the Inside <head> tag custom code section of the page settings.

Open the Body Code (Delete After Copying) embed, copy the code and place it in the Before </body> tag custom code section of the page settings.
Step 2: Connect CMS Collection to Slider (Optional)
Find the div block with class .slider06_component and add a Collection List inside of it.

Add the combo class slider06_wrapper slider-wrapperto the Collection List Wrapper

Add the combo class slider06_list slider-listto the Collection List

Add the combo class slider06_item slider-item the Collection Item

Find the existing div block with class .slider06_wrapper and delete it. (Your CMS Collection List now replaces this)
Step 3: Renaming Classes
We recommend to use {Finsweet Folders from the {Finsweet Chrome Extension to quickly update your class names for this section. Using the Folders tool, you can find and rename all instances of slider06 within the project.

Please make sure that the following combo classes stay applied to the specified elements:
slider-wrapper is applied to the Collection List Wrapper or Div Block containing the slider-list and
slider-list is applied to the Collection List or Div Block containing the slider-item
slider-item is applied to the Collection Item or Div Block for each individual slide
Optional: Delete slider06_arrows to remove the custom navigation arrow buttons.
Optional: Use slick-current as a combo class on the slider-item to style the currently highlighted/focused slide.
Step 4: Style Away!
We recommend adding a slider06_contents div block to the slider-item and then add images, text, and custom styling as necessary to achieve the look you are going for.

Please note that some aspects of the design of the slider will come from the "settings" in the slider code, such has number of slides displayed at each breakpoint. If you are trying to make significant changes from the base structure of this slider, please make sure to review the different setting options that SlickJS offers.

“Incidence Sails developed a strong, reliable and long-lasting relationship with the C-Tech products over the years, specially through the supply of the CT SailBattens range that have always matched and exceeded our highest expectations in terms of durability and stiffness compliance to our specifications. Last but not least the supply chain works perfectly even during tricky times.”

Cesar Dohy
“For over 20 years, C-Tech has consistantly delivered quality products and a professional service. We know we can rely on their composites but it's the in-house experience that really adds value. Despite being on the other side of the world, C-Tech is always on hand with advice and support.”
One Sails
John Parker, GBR
“Doyle Sails works with a significant number of Grand Prix race yachts and Superyachts globally and in nearly every project C-Tech is on-board as our supplier for carbon battens and systems. A very high quality, performance product, proudly made in New Zealand, led by a team of engineers who are constantly innovating - it is a pleasure to work with C-Tech.”
Doyle Sails
“We’ve had our C-Tech SnuffAir for 12 months now and have used it flawlessly. It’s even better than I expected actually, this is a massive sail and personally I don’t think you could beat this”
Romanza Owner

Dougall Love
“C-Tech’s flexibility in design and build, combined with a willingness to collaborate on ideas, helped in producing the best components for our needs, giving us the best results.”
ETNZ

Rig Construction Coordinator
“Battens play a key role in the performance of the sails. If the shape of the batten does not exactly match the shape of the sail, they fight each other and that can be quite detrimental. They must be light and strong. C-Tech are able to build specified stiffness and bend profiles very accurately and repeatedly.”

“C-Tech products are phenomenal. Our boat has gone better than it ever has before. Every one of their products is integral to our boat speed and durability in both cruising and racing.”
P2 Team (Briand 123)
“It has been a game changer switching to FlexiFurls. They have given us true race performance in our furling sails. Also the service has been tops, so really happy all around.”
Peter Homberg
“We like using C-Tech battens with our grandprix and large yacht sails. The fasteners and hardware are corrosion resistant, rust free and provides easy sail care for us and our customers. The battens and hardware are engineered and make by sailors for sailors, they work perfect every time.”
Ullman Sails, IncBruce Cooper
“C-Tech has been our trusted supplier for battens and batten hardware for over ten years.”
One Palma
“We have used your product for many years and you know we call your battens a bit of a magic wand. They are a tool, but are hidden within the sail and you don’t see them. Just like there are so many bad tools out there, there are also so many bad battens. C-Tech battens are the tool that can actually make a bad sail look better, and make a good sail look great.”

Advantages of Carbon Composites

How carbon enables better

solutions for marine.

Carbon fibre outperforms traditional materials where it matters most. Our composites are lighter, stronger, more resilient — and engineered for the demands of real-world marine environments.

Up to 70% lighter than metals — with no compromise on strength. Ideal for range-critical, airborne, or mobile systems.
Superior strength-to-weight ratios mean better payloads, longer endurance, and greater operational flexibility.
Carbon fibre holds up under pressure — from high temps to saltwater to repeated impact.
From concept to part in record time. Our agile production model supports rapid development cycles — perfect for early-stage defence innovation.
