Welcome to Caina-Longbranch Defence Systems.

Defence Contractors Since 1985

Although all sections listed are active and are at least partially populated this website has been evolving as of late 2010 when it was finally launched for the first time for our group of companies.  Due to the range and complexity of our equipment line, if you do not see what you are looking for or need further information please contact us with additional specific requests until we are able to fully populate the website. For live links and more information please go to the Ordnance & Ammunition side bar and click on the live links 

If we have not dealt with you before and due to the nature of our business, please formally  intoduce your company or yourself as per the contact information on this page. We are somewhat "Old School" for very practical reasons. We receive numerous enquiries and so that we can focus our attention properly for real needs we must sort out legitimate enquiries, from adventurers, information gatherers and people who are not even licienced to carry out the business that they are inquiring about. Both of our time, overhead and resources are of value and should be respected. The more effort that is put into an inquiry along proper business format, the more attention it receives from our company.


For preliminary inquires, qualified operators and buyers are most welcome to contact us by e-mail with the following form provided for your convenience. It is understood that proper identification and documentation, if applicable, will be required at time of ordering depending on the equipment in question. We aim to respond to enquiries in a timely manner.


N.B. April 2014: We continue to receive many inquiries that simply ignore the above formal contact procedure requested

We ask that companies properly introduce themselves as we are pelted with inquiries from teenage boys in Southern California sitting in their underwear in their parents basement, behind a computer, working to build their own private armies. These unlicensed and unauthorized inquiries are expensive and time consuming for us to separate the "wheat from the chaff" and focus on legitimate inquiries of people over voting age. On a more serious note our experience for the last 28+ years has proven that an inquiry that has a more formal effort put into it usually leads to a more productive & successful outcome for both parties.
