The Russian Ministry of Defense released on Thursday videos of five new weapon systems, which Russian President Vladimir Putin bragged would render make US missile defenses "ineffective" in a March address.
The new weapons included a new intercontinental ballistic missile, a global cruise missile, a nuclear torpedo, a hypersonic plane-launched and nuclear-capable missile, and a laser.
"They kept ignoring us," Putin said about the West in his state of the union address after describing the weapons. "Nobody wanted to listen to us, so listen to us now."
Although Putin boasted about the weapons during his speech, many have been skeptical about some of the new systems.
Here are the newly published Russian MoD videos, and what we know about the weapons:

The Sarmat is a liquid-fueled intercontinental ballistic missile that Putin claimed had an unlimited range and could beat any air defenses.
Meant to replace the SS-18 Satan, the Sarmat is silo-based and has several payload options, including 10 large warheads or 16 small warheads or a combination of warheads and countermeasures.
It appears to have been successfully tested in late March, and is expected to be fielded by 2020-2021.
