Preface

28th International Symposium on Ballistics,Atlanta,GA,USA,22-26 September 2014

This is the first issue of Defence Technology to publish scientific papers presented at the 28th International Symposium on Ballistics(ISB),organised by the National Defense Industrial Association(NDIA,www.ndia.org)under the auspices of the International Ballistics Society(IBS,www.ballistics.org).

The ISB is an opportunity for ballistics scientists,engineers,and others to report,share and discuss current research and advances in ballistics and visions for the future.The symposium allows exposure to the most current state-of-theart technology in ballistics,provides opportunities for interactions with some of the world's leading experts in the field of ballistics technology,and offers the chance to present,exhibit,and share scientific research and development with an international group of professionals.

The Society encourages the presentation of a wide range of papers at the ISB,from work in progress through to high quality scientific papers.This issue of the journal includes 21 of these scientific papers,which have been rigorously peer reviewed and approved according to the practises of the journal.

These papers comprise an extensive range of ballistic science areas covered by the symposium;interior ballistics and fl ight dynamics,explosion mechanics,terminal ballistics and impact physics,and vulnerability.

I am sure you will find these papers stimulating and very interesting.Defence Technology provides an opportunity to develop an understanding of the total realm of ballistic science outside of the reader's specialist area.I therefore commend this issue of the journal to you.
