Lynx IFV armament

KF 41 – Huang Yimin

The Lynx IFV is mounted with a Rheinmetall LANCE turret armed with a stabilised and externally-powered 30mm or 35mm automatic cannon. The turret allows the crew to effectively engage targets at a maximum distance of 3,000m.

30 mm x 173 / 35 mm x 228 WOTAN30 / WOTAN35

The WOTAN30 is an externally driven, medium-calibre automatic cannon with a rate of fire of 200rds/min. Easy to handle and highly reliable, the WOTAN30 can neutralize a wide variety of targets, making it the perfect choice for arming modern IFVs and other combat vehicles. The WOTAN35 is the latest member of the new WOTAN family and, due to its larger calibre, delivers longer range and deeper penetration than 30mm cannons. Source rheinmetall-defence.com

Rafael Spike LR2 ATGMs

KF 41 – DTR Magazine

Spike-LR II is smarter, sharper and agiler than its predecessors, but is designed to operate from the same launchers used for Spike MR and LR, in dismounted configurations, on vehicles, weapon stations, marine platforms, and helicopters. It will also fit the new lightweight launcher developed by RAFAEL for aerial platforms, enabling light helicopters to defeat tanks, vehicles or bunkers from ten kilometers away. The new missile will be presented for the first time at the Paris Air Show in June.

Weighing 12.7 kg – 10% less than the legacy LR, Spike LR II provides major enhancements over the current LR variant -in lethality, range, and resolution. First and foremost, the new version enhances the Spike’s capability to defeat targets of all types – from main battle tanks with advanced, reactive and active protection, to fortified and evasive targets and those hidden in bunkers, buildings.

RAFAEL offers the missile with a choice of two warheads – an anti-tank missile optimized with an enhanced tandem warhead that increases armor penetration by 30 percent over the previous generation. Another advantage of the new missile is its ability to strike at higher impact angles – Spike LR II will be able to hit targets at up to 70 degrees, delivering more lethal top attack profile. According to RAFAEL, the SPIKE LR II is the only missiles known to have an inherent Counter-APS (CAPS) capability.

The second type is the multi-purpose version, provided with a different tandem warhead using multiple fusing presets designed to defeat light or fortified targets. The variable fusing enables the operator to set the fuse to penetrate a target or explode on impact. Designed to operate as a penetrating warhead, the missile’s warhead would breach a small hole through reinforced concrete, for the main charge to follow through.

The missile maintains the fiber-optic data link for man-in-the-loop control but the new missile can defeat those targets from an extended range of up to 5,500 meters. Source defense-update.com
