Dear Messrs. Knight and Bartelmes:

We are writing to respond to the comment set forth in the comment letter of the Staff of the Securities and Exchange Commission (the “Staff”), dated June 5, 2008, relating to the above-referenced document.

For your convenience, we have reproduced the Staff’s comment in this letter using bold text and numbered the paragraph of this letter to correspond to the numbered paragraph of the comment letter.

Definitive Proxy Statement Incorporated By Reference Into Part III of Form 10-K

Compensation Discussion and Analysis, page 30

1. Throughout your Compensation Discussion and Analysis and as to each compensation element, disclose in future filings how you arrived at and why you paid each of the particular levels and forms of compensation for each named executive officer. For example, on page 34 you disclose certain factors that the committee considers when setting annual bonus amounts. However, we believe it is appropriate to provide a more thorough analysis how these factors were analyzed and why the committee’s analyses resulted in the compensation they paid.

In response to the Staff’s comment, L-3 advises the Staff that L-3 will disclose in future filings a more thorough analysis of how it arrived at and why it paid each of the particular levels and forms of compensation for each named executive officer.

Mr. Jay H. Knight

Sincerely,
