The Mechanical and Chemical Industry Corporation (Turkish: Makine ve Kimya Endüstrisi or MKE for short), established in 1950, is a reorganization of government-controlled group of factories in Turkey that supplied the Turkish Armed Forces with military products.

Its roots lie in the "Tophane-i Amire" ("Royal Arsenal") built in the latter part of the 15th Century to supply the Ottoman Empire's artillery corps with cannon, powder, and shot.

This was reorganized in 1832 as the "Tophane Müşavirliği" ("Arsenal of Ordnance and Artillery Marshalship") and was later formed in a department of "Harbiye Nezareti" (Ministry of War) in 1908.

Its large range of defense industry products are not only demanded in Turkey, but are exported to more than 40 countries worldwide.
