Impulse and Stores-Ejection Cartridges: Exploring the Product Families
Our cartridge portfolio includes CCU and BBU impulse cartridges alongside MK-series stores-ejection cartridges. These names describe distinct products and application families, not a set of interchangeable devices. Here is how the portfolio is organized and how it fits into the wider language of energetic cartridges and CAD/PAD.
The impulse-cartridge family
The impulse-cartridge portfolio includes CCU-136A/A, CCU-145/A, BBU-36/B and BBU-48A/B. The individual product pages are the place to explore each item; the family name is a starting point rather than a complete product description.
Aircraft countermeasure dispensing is one of the applications represented in our energetics portfolio. The distinction between a cartridge and the equipment around it remains important: a cartridge contributes to a function in a larger arrangement. The photograph accompanying this article illustrates that application context, not the identity of a cartridge supplier.
MK-17 and MK-107 stores-ejection cartridges
MK-17 and MK-107 appear in our stores-ejection and actuation portfolio. Keeping that application label visible helps readers distinguish these products from other energetic-cartridge families.
Similar terminology or appearance is not evidence of compatibility. Product identity and the applicable program documentation matter more than a broad category name. Readers can explore the MK-17 and MK-107 pages for the individual product information.
Where CAD/PAD fits
CAD/PAD stands for cartridge-actuated devices and propellant-actuated devices. NAVAIR describes a broader category of energetic devices used within systems, including aircrew escape equipment. The acronym is not another name for every cartridge, nor does it describe a complete system by itself. NAVAIR CAD/PAD overview
An impulse cartridge, an assembled device and a complete ejection system therefore represent different levels of description. Understanding those levels makes product information easier to navigate without assigning a particular application or approval on the strength of an acronym.
Beyond the product name
Cartridge manufacturing also brings together components, assembly, inspection and documentation. Our manufacturing capabilities and quality and testing pages describe that supporting work.
When discussing an existing product or custom manufacturing requirement, identify the item or scope, quantities, timing and documentation needs. That gives the program team a clearer starting point than a general request for “energetic cartridges.”
