Recently, the United States signed an arms trade contract with Greece to cater to the development plans of the Greek Navy and to balance arms sales to Turkey. The contract marks the U.S. commitment to Greece's deeper military development and plans to provide it with cutting-edge equipment, including F-35 fighter jets, as well as support for strengthening naval buildup. Further, the United States even decided on the feasibility of joint production of Constellation-class frigates with Greece. The U.S. Navy has already confirmed in a letter of winning the bid that Greece has expressed strong interest in this option. 
The Constellation-class frigate is a new generation of frigates of the U.S. Navy, which uses an advanced diesel-electric-fuel combined power propulsion system. This propulsion system combines a gas turbine, propulsion motor, diesel generator and auxiliary propulsion system to ensure superior power performance and fuel economy in a wide range of environments and sailing conditions. In terms of detection capabilities, the Constellation-class frigates are equipped with the top-of-the-line AN SPY-6 phased array radar system. The radar's high resolution and fast scanning capabilities provide ships with accurate target detection and tracking capabilities. In addition, it is equipped with the NGSSR sea search radar and the AN SLQ-32 (V) 6 electronic warfare system, which ensures comprehensive battlefield awareness and powerful electronic countermeasures capabilities. 
In terms of ** systems, the "Constellation" class frigates are equipped with 4 groups of 8 units with a total of 32 units of MK41 vertical hair systems. This allows it to launch a wide range of missiles, including the Standard SM-2 long-range anti-aircraft missile, the Tomahawk land-attack cruise missile, and the VLA rocket-assisted torpedo. These ** combinations give the ship powerful anti-aircraft, anti-ship and anti-submarine warfare capabilities. In addition, a MK-110 57mm single-barreled naval gun of the MK-57 type is installed in the front of the ship, which has high-precision and high-speed firing capabilities, capable of effectively striking enemy ships and coastal defense facilities. The rear of the ship is equipped with a 21-pack "Ram" short-range air defense missile system to provide short-range air defense protection for the ship. In the central part of the country, four 4-mounted NSM anti-ship missile systems are installed, which have high speed and long-range strike capabilities and are capable of posing a significant threat to the enemy's fleet and transport lines. 
Over the past few years, rumors of the purchase of Constellation-class frigates by Greece have been in the spotlight. There is speculation that Greece may have some kind of partnership with LCS MMSC. And at the 2024 European Naval Defense Exhibition, the United States even launched a Europeanized version of the "Constellation" class frigate, which is obviously tailored for Greece. This European version of the Constellation-class frigate is more compact in size, with an expected displacement of about 5000 tons and a length of almost 140 meters. Despite its reduced size, its firepower is still as powerful as the original "Constellation" class, with the same number of 32 vertical hair units. It is worth mentioning that the European version of the "Constellation" class frigate has more powerful gun firepower than the original, armed with a 76 mm or 127 mm main gun. 
For a small country like Greece, the purchase, equipping, equipping, and maintenance of seven Constellation-class frigates would be a huge expense. As a result, U.S. Navy News speculates that if the new ships are built, they will most likely be an improved version of the Constellation-class rather than an exact replica. Achieving the same firepower with a smaller tonnage, this will be more in line with the real needs of the Greek Navy. 
However, the United States** also reminds us that over the past few decades, the Greek Navy has repeatedly put forward ambitious development plans, but often failed to achieve them. For example, the procurement program for 6 MEKO 200 and 6 FREMM frigates ultimately came to nothing. Therefore, there is still a great deal of uncertainty about whether the large order for 7 "Constellation" class frigates can really be implemented.
