The total estimated value was $200 million. Major Defense Equipment (MDE) constituted $100 million of this total.
On November 20, 2019, Congress was notified by congressional certification transmittal number 1J-19, under Section 36(b)(5)(A) of the Arms Export Control Act, of the addition of the following MDE: 1) twenty (20) MK 54 All Up Round Lightweight Torpedoes; and 2) two (2) MK 54 Exercise Torpedoes (EXTORPS) (MK 54 Kit Procurement Required). Also included were MK 54 LWT Spares; torpedo containers; Recoverable Exercise Torpedoes (REXTORP) with containers; Fleet Exercise Section (FES) and fuel tanks; air launch accessories for fixed wing; torpedo spare parts, training, publications, support, and test equipment; U.S. Government and contractor engineering, technical, and logistics support services; and other related elements of logistics and program support. The addition of these items resulted in a net increase in MDE cost of $19 million, resulting in a revised MDE cost of $119 million. The total estimated case value increased to $240 million.
This transmittal notifies the inclusion of the following additional MDE items: twelve (12) MK 54 MOD 0 Lightweight Torpedo all up rounds. The following non-MDE items will also be included: torpedo containers; Recoverable Exercise Torpedoes (REXTORP); Fleet Exercise Sections (FES) and fuel tanks; U.S. Government and contractor engineering, technical, and logistics support services; and other related elements of logistics and program support. The estimated total value of the new MDE items is $40 million, resulting in a revised estimated MDE value of $159 million. The estimated total value of the new non-MDE items is $15 million, resulting in a revised non-MDE value of $136 million. The estimated total case value will increase by $55 million to $295 million.
(iv) *Significance:* This notification is being provided because the additional items were not enumerated in the original notification. The proposed sale will improve Denmark's capability to meet current and future threats.
(v) *Justification:* This proposed sale will support the foreign policy goals and national security objectives of the U.S. by improving the security of a NATO Ally that is a force for political stability and economic progress in Europe.
(vi) *Sensitivity of Technology:*
The MK 54 Lightweight Torpedo is a conventional torpedo that can be launched from surface ships, rotary and fixed wing aircrafts. The MK 54 LWT is an upgrade to the MK 46 Torpedo that entails replacement of the torpedo's sonar and guidance and control systems with modem technology. The new guidance and control system uses a mixture of commercial-off-the-shelf and custom-built electronics. The warhead, fuel tank, and propulsion system from the MK 46 torpedo are re-used in the MK 54 torpedo configuration with minor modifications.
The highest level of classification of defense articles, components, and services included in this potential sale is SECRET.
