Are the SIZZER and SUNBURN missiles history?
The Russian packages are very diverse in their products.
They still use the Sizzler as a sub launch. Both the SS-N-27 Sizzler or 3M-54 Klub missile are designed to destroy submarine and surface vessels, but can do other things as well.
They use their Kh-55 as their template for most of their arsenal as they have created one for every need it seems over the years. They have even publicly come out with the Kh- 101/102 that has conventional or thermonuclear. This little cutey is equipped with an electro-optical system for correcting the flight trajectory and with a TV guidance system for terminal guidance It is scheduled to be in production and use by 2023.
