Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	b. Basis of presentation: The accompanying interim condensed consolidated financial statements have been prepared by Arotech Corporation in accordance with generally accepted accounting principles for interim financial information, with the instructions to Form 10-Q and with Article 10 of Regulation S-X, and include the accounts of Arotech Corporation and its subsidiaries. Certain information and footnote disclosures, normally included in complete financial statements prepared in accordance with generally accepted accounting principles, have been condensed or omitted. In the opinion of the Company, the unaudited financial statements reflect all adjustments (consisting only of normal recurring adjustments) necessary for a fair presentation of its financial position at June 30, 2015, its operating results for the six- and three month periods ended June 30, 2015 and 2014, and its cash flows for the six month periods ended June 30, 2015 and 2014. The results of operations for the six and three months ended June 30, 2015 are not necessarily indicative of results that may be expected for any other interim period or for the full fiscal year ending December 31, 2015. The balance sheet at December 31, 2014 has been derived from the audited financial statements at that date but does not include all the information and footnotes required by generally accepted accounting principles for complete financial statements. These condensed consolidated financial statements should be read in conjunction with the audited financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014.
Reclassification, Policy [Policy Text Block]	c. Reclassification: Certain comparative data in these financial statements may have been reclassified to conform to the current year’s presentation.
Commitments and Contingencies, Policy [Policy Text Block]	d. Contingencies The Company is from time to time involved in legal proceedings and other claims. The Company is required to assess the likelihood of any adverse judgments or outcomes to these matters, as well as potential ranges of probable losses. The Company has not made any material changes in the accounting methodology used to establish its self-insured liabilities during the past three fiscal years. A determination of the amount of reserves required, if any, for any contingencies is made after careful analysis of each individual issue. The required reserves may change due to future developments in each matter or changes in approach, such as a change in the settlement strategy in dealing with any contingencies, which may result in higher net loss.
Related Party Policy [Policy Text Block]	e. Certain relationships and related transactions Officer loans: On February 9, 2000, one of the Company’s officers exercised 9,404 stock options. This officer paid the exercise price of the stock options and certain taxes that the Company paid on his behalf by giving the Company a non-recourse promissory note due in 2025 in the amount of $329,163, bearing annual interest at 1% over the then-current federal funds rate announced from time to time by the Wall Street Journal, secured by the shares of the Company’s common stock acquired through the exercise of the options and certain compensation due to this officer upon termination.

Additionally, there is a former employee with the same arrangement with an outstanding promissory note of $455,059. Consulting agreement with Sampen Corporation: The Company has a second amended and restated consulting agreement with Sampen Corporation that it executed in November 2014. Sampen is a New York corporation owned by members of the immediate family of one of the Company’s officers, and this officer is an employee of both the Company and of Sampen. The term of this consulting agreement is until December 31, 2017.

The Company pays Sampen $8,960 per month, plus an annual bonus, on a sliding scale, in an amount equal to a minimum of 25% of Sampen’s annual base compensation then in effect if the results the Company actually attains for the year in question are 100% or more of the amount the Company budgeted at the beginning of the year, up to a maximum of 75% of Sampen’s annual base compensation then in effect if the results the Company actually attains for the year in question are 110% or more of the amount the Company budgeted at the beginning of the year.

Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	f. Accounting for stock-based compensation: For the six months ended June 30, 2015 and 2014 the compensation expense recorded related to restricted stock units and restricted shares was $335,000 and $258,000, respectively.

The weighted average period over which this compensation cost is expected to be recognized is approximately one and one-half years. Income tax expense was not impacted since the Company is in a net operating loss position. There were no new options issued in the first six months of 2015 and there are no outstanding issued options. The Company’s directors received their annual restricted stock grants on April 1, 2015 in accordance with the terms of the directors’ stock compensation plan.
Earnings Per Share, Policy [Policy Text Block]	g. Anti-dilutive shares for EPS calculation All contingent and non-vested restricted stock and non-vested restricted stock units have been excluded from the calculation of the basic earnings per common share because all such securities do not participate in losses for the periods presented and have been excluded from the calculation of diluted earnings per common share as the effect would be anti-dilutive. The Company has excluded any restricted stock or restricted stock units that will never vest under the current program. The total weighted average number of shares related to the outstanding options and warrants excluded from the calculations of basic and diluted net income per share for the six month periods ended June 30, 2015 and 2014 were 1,015,654 and 602,740, respectively.
