MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING To the Shareholders of General Dynamics Corporation: The management of General Dynamics Corporation is responsible for establishing and maintaining adequate internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Our internal control system was designed to provide reasonable assurance to our management and board of directors regarding the preparation and fair presentation of published financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Our management evaluated the effectiveness of our internal control over financial reporting as of December 31, 2020. In making this evaluation, we used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in  Internal Control – Integrated Framework (2013) . Based on our evaluation we believe that, as of December 31, 2020, our internal control over financial reporting is effective based on those criteria. KPMG LLP has issued an audit report on the effectiveness of our internal control over financial reporting. The KPMG report immediately follows this report. Jason W.
