The evidence against the Kirov (Modernized) mounted and it painted a picture of a fairly ineffective design for the needs of the Chilean Navy. The Chilean Navy didn't really want a battlecruiser, it more wanted something much like the old Kiev Class aircraft carrying cruiser. What was decided upon was to dispose of the Kirovs and acquire four heavy ships of the line designed to fill the modern role of a battleship with advanced weapons, AESA radar, and missiles. The other ships were to be based around the idea that not all situations required the deployment of an entire Carrier Strike Group.
Most recent situations, diplomatic visits, and so forth were resolved by the ill-suited Kirov designs. A ship armed with reasonable supply of anti-shipping missiles, cruise missiles, a marine detachment, and a flight deck would be built to take up the role of multi-purpose ship that could be used for all occasions. The designers at work are well aware that a ship that generalizes in everything, specializes in nothing, which would clearly prove to be a significant limitation to the design should it become embroiled in a large scale engagement.
Yet, in the role of first response to natural disasters, dealing with armed conflicts in nations significantly weaker than Chile, and anti-piracy operations the ships would be most ideal. The three ships could operate alone or within a larger formation. They could act as a significant force multiplier when complemented by a small number of lighter classes. In essence the ships are projected to be a significant cost saver for situations that just do not require the deployment of a fleet or battlegroup.
