1B77 Ulybka-M

Also known as
  • 1B77
  • 1Б77
  • Ulybka-M
  • Улыбка-М

The 1B77 Ulybka-M is a Russian mobile radio-direction meteorological complex in the Ulybka military weather-support family. Public sources tie the system to OKB Peleng development work, UPP Vector supply activity, and a KamAZ-6350 apparatus vehicle with a light-gas trailer. Its role is to collect upper-air and surface meteorological data for artillery, rocket, missile, aviation, airborne, and CBRN users rather than to act as a strike system itself.

Meteorological Support Role

Ulybka-M belongs on the catalog as support equipment: its public mission is to generate meteorological data used by other military systems, not to deliver effects on a target directly. The stronger sources describe a weather-data chain for fires, missiles, aviation, airborne operations, and CBRN calculations while keeping combat-use claims separate from the older 1B44/RPMK-1 record.

Fires support

Russian reporting says Ulybka-M data can support tube artillery, rocket artillery, operational-tactical missile systems, and tactical missile systems.

Measured environment

The published technical list covers surface temperature, wind, humidity, visibility, pressure, near-surface stability, and upper-air wind, density, temperature, cloud-base, humidity, and pressure values.

Operating modes

The same report separates radio-direction and radar modes, with different radiosonde sets and output documents for each mode.

Compact successor

Patent material identifies RPMK-1 Ulybka as the predecessor and describes a mobile aerological design aimed at reducing the work and time needed to prepare radiosonde operations.

Industrial chain

OKB Peleng disclosure material supports development work, while TASS identifies AO UPP Vector and Almaz-Antey context for the 2017 Ministry of Defence supply agreement.

Variants

Public sources treat 1B77 Ulybka-M as the later KamAZ-based Ulybka-family successor to the older RPMK-1 / 1B44 arrangement.

The 2017 delivery report says Ulybka-M replaced the older 1B44 Ulybka layout, while the RU2634486C2 patent treats RPMK-1 Ulybka as the predecessor arrangement for a more compact mobile aerological complex.

Public reporting describes the system as a multi-vehicle package with a radar/antenna vehicle, command or operator-control vehicle, and power-support vehicle on KamAZ chassis, while Rosoboronexport markets the export Podlet-K1KE for automated detection, tracking, identification, and flight-information tasks in air-defense and air-force radio-engineering units. Ukraine-war reporting documents Russian Podlet-K1 losses and strikes tied to the S-300 and S-400 air-defense network.

Public product data and technical reporting describe a KamAZ-4350 based system that determines horizontal coordinates and elevations while moving or stopped, transfers coordinates to surveyed points, and supports troop movement routes, geodetic-network recovery, and operational navigation-geodetic support. Russian-state reporting also names PNGK-1 among systems used by Russian military topographers in the 2022 phase of the 2014 Russia-Ukraine War.

Open reporting describes it as a phased-array artillery reconnaissance system on a BAZ-6910-025 8x8 chassis, built to track incoming shells or rockets and calculate artillery firing positions for counter-battery fire. Russian state-linked reporting announced its use with Russian artillery units in Ukraine in January 2024, while Ukrainian military, government-linked, and independent news coverage later documented the destruction of multiple Russian Yastreb-AV systems.
